The correct one is M x N - C + F.

Read it from left to right.

M x N → M is the father of N
(M is the dad of N)

N - C → N is the sister of C (N is sis of C, so C must be a boy)

C + F → C is the brother of F(confirms again, C is a boy)

Let’s pull it all together;
M x N → M is dad of N.

N - C → N is the sister of C → So C is also a child of M, since N and C are siblings, and M is the dad.

C + F → C is the brother of F → confirms C is male.

So C is the son of M.

Final Breakdown:
Person -- Relation
M -- Father
N -- Daughter
C -- Son (our target 🎯)
F -- C's sibling (no gender needed)

So, the Final answer:
M x N - C + F.
C is the son of M!

A is bro of B (if +),
A is sis of B ( if -) ,
A is the father of B (if x).

The question says what equation says the C is the son of M.

By Cross-checking, we got a hint. (A × B - a is the father of B)

Our question is to check whether C is the son of M.
Or (M is the father of C)

So, Option D is correct.
