Explanation

In C, the comma operator evaluates its left operand, discards the result, and returns the right operand. Thus, c = a, b; binds as (c = a), b; due to operator precedence, setting c to 3. Meanwhile, d = (a, b); evaluates the group, setting d to 5. The printed output is c = 3 and d = 5, which is matches option '3,5'.
