Concept:
- Apply every eligibility condition to each candidate one by one and reject a candidate the moment one condition fails.
- "More than 2 years" means strictly greater than 2 years; exactly 2 years does not satisfy this condition.
Step 1: Check the marks condition (minimum 60%).
A = 73% (passes), B = 67% (passes), C = 70% (passes), D = 55% (fails, below 60%).
D is rejected.
Step 2: Check the age condition (not more than 30 years).
A = 30 years (passes, exactly at the limit), B = 31 years (fails, exceeds 30), C = 29 years (passes).
B is rejected.
Step 3: Check the experience condition (more than 2 years).
A has exactly 2 years of experience, which is not "more than 2 years", so A fails this condition.
C has 3 years of experience, which satisfies the condition.
Step 4: Identify who survives all three checks.
Only Candidate C clears the qualification, age and experience conditions together.
Final Answer: Candidate C (option 3)
