Answer 1

Correct Answer - Option 4 : B

Four friends A, B, C and D meet at their alumni get-together. One of them is a doctor whereas the other three are engineers.

A says, ‘C is an engineer'.

B says, ‘Neither A nor D is the doctor’.

C says, ‘I am not the doctor’.

D says, ‘C is telling the truth’.

If all four of them are speaking the truth, then persons with their profession is shown below:

Person	Profession
A	Engineer
B	Doctor
C	Engineer
D	Engineer

Clearly, B is the doctor.

Hence, ‘B’ is the correct answer.
