Respected Ankit sir, so the second statement is incorrect so why it is given that it is correct

Dear Student, 

A - Grammatically incorrect. The correct statement is :
Jenny and Sara are swimming champions. 
B- If ' Ball and balloon ' represents a single idea, the statement can be considered grammatically correct.
However, if they refer to the materials ball and balloon then it is grammatically incorrect. So for this option, a case can be made out and it can be considered grammatically correct. 
C- Grammatically correct. 
D- Incorrect. 
The correct statement is :
Are Kabir and Samaira coming to the party? 

So the question has multiple answers.
