What can you conclude regarding the situation given below?
Three ladies X, Y, and Z marry three men A, B, and C. X is married to A. Y isn't married to an engineer. Z isn't married to a doctor.

This is a test of logic and attention to detailed instructions. Options B and D can be ruled out because both contradict the information given in the question. Option C could be correct as there is nothing in the question that rules out the possibility that X married a doctor.

Equally, it could be incorrect if one of the other women married a doctor, but we don't know their choices. If one of them married a doctor than option A would be correct, i.e. that none of the options A to D is true.

There are clear instructions on who the lawyer, doctor, and engineer are but none of the statements just seem to fit well. A is a lawyer which means that X married a lawyer.

Y is not married to an engineer which means that Y is married to a doctor and Z is married to the engineer. Based on all of the things that you have learned, it is safe to conclude why none of the statements are correct.
