The correct answer is (C): 3142.
3. Seven popular Japanese deities, the Shichi Fukujin, were considered to bring good luck and happiness.
1. Each one personified a different aspect of good fortune.
4. Although they were included in the Shinto pantheon, only two of them, Daikoku and Ebisu, were indigenous Japanese gods.
2. The others were versions of popular Buddhist gods, Hindu gods and Daoist gods.
We should initiate this arrangement by incorporating the pronoun "each one" in sentence 1, which states "each one personified a different aspect of good fortune". This statement directly relates to sentence 3, which introduces the "seven popular deities... Considered to bring good luck and happiness". Hence, the concepts presented in sentences 3 and 1 are similar, with sentence 3 serving as an introduction and sentence 1 elaborating on the idea further. On the other hand, sentences 4 and 2 constitute another cohesive unit. In sentence 4, we encounter the phrase "only two of them were indigenous Japanese gods", while sentence 2 mentions "the others were...". The juxtaposition between the two indigenous gods and the other Buddhist gods establishes a connection between sentences 4 and 2.
So, the correct option is (C): 3142
