The facts say Mr. A declared Ms. C as his wife in front of colleagues, family and relatives, but nothing in the facts describes any actual ceremony or rite being performed. That gap is exactly what the Lokhande principle turns on.
Without an actual solemnisation, however sincere or public the declaration, there is no marriage in the legal sense, and therefore no bigamy under Section 494.
So the correct answer is (C): Mr. A is not liable for the offence of bigamy as he has not solemnised his marriage with Ms. C.
The word "solemnise" is doing a lot of legal work in this area, since whether a marriage is solemnised decides whether Section 494 of the Indian Penal Code, 1860 can apply at all. The passage and the Lokhande case both use the word in a specific, narrow sense.
Solemnisation is the concrete, ceremonial act that gives a marriage legal existence, which is why the courts treat it as essential rather than as sentiment, paperwork, or an optional formality.
So the correct answer is (A): Solemnisation means celebrating the marriage with proper customary rites and ceremonies of either party to a marriage.
This question asks which statement about monogamy under Hindu law is wrong, and the passage is specific about what the Hindu Marriage Act, 1955 actually did to the law of monogamy, which makes one option easy to spot as reversed.
The Act of 1955 is the point at which monogamy became the legal rule for Hindus, so describing it as the point of abolition gets the history exactly backwards.
So the correct answer is (B): Monogamy as a law was abolished after 1955.
Three of these four options describe what Section 13 of the Hindu Marriage Act, 1955 actually provides, while one of them is simply an opinion about whether the provision should exist, which is a different kind of statement altogether.
A, C and D are all attempts to describe features of the remedy itself, while B steps outside that and argues a policy position about whether the ground should exist at all, which is why B is the one that does not relate to the remedy.
So the correct answer is (B): The introduction of this ground of divorce is unnecessary as it disturbs the sanctity of marital institution.
The trick in this fact pattern is the conversion. Mr. P does not divorce Ms. Q, he simply converts to Islam and then goes through a second marriage with Ms. N. The question is whether that conversion lets him escape the bigamy rule that would otherwise apply to a Hindu husband.
A conversion to another religion does not, by itself, end an existing Hindu marriage, so a second marriage contracted after that conversion, while the first marriage still stands, remains bigamy in the eyes of the law.
So the correct answer is (D): Yes, Ms. Q has the remedy of filing a complaint for the offence of bigamy.
