Answer 2

Answer:

A is the son of C.

Explanation:

Given ‘X + Y’ means X is the father of Y,

  And ‘X – Y’ means X is the mother of Y,

In C – A + B,  

 A + B means A is the father of B.

 From C – A means C  is the mother of A.

  A is the father, so A  is a male.

Therefore, A is the son of C.

Hence, the correct answer is option C.
