Solution(By Examveda Team)
When the birds sat one on a branch, there was one extra bird. When they sat Two to a branch one branch was extra. Now, we go through the options; Checking option (A); If there were 3 branches, there would be 4 birds. (This would leave one bird without branch as per the question.) When 4 birds would sit Two to a branch there would be one branch free (as per the question.). Hence, the option (A) is correct.Join The Discussion
