Text Solution

Verified by Experts

The correct Answer is:
D
I+I= No conclusion Hence, no definite conclusion can be established between trees and balloons.. This negates II, III and IV. But III and IV are an I-E pair or a complementary pair. So, one of them must be true. I does not follow in any way. Thus, a suitable choice is not given
