F---------E(Brother)

a)E is the grandson of A  True         b)F is the daughter of C false

c)B is the father of F True    d)There are one son and one daughter in the group False

e)C is the uncle of E True

Hence option B)a,c,e are true is right ans

• $C$ is the brother of $D$’s husband and son of $A$, which means $B,D$ are a couple and $A$ has 2 male children $B,C$.
• $F$ is the daughter of $D$ and sister of $E$, which means $B, D$ have 2 children $E, F$

• $E$ is the grandson of $A$, true.
• $F$ is the daughter of $C$, false F is $B, D$’s daughter.So option $A,C,D$ are wrong.
• $B$ is the father of $F$, true.
• There is one son and one daughter in the group, false.
• $C$ is the uncle of $F$, true.

So option (B) is correct here.
