Solution

The correct option is A
29

Numbers that are greater than 1, and are only divisble by 1 and the number itself are called prime numbers.

The pattern of prime numbers starting from 7 is

7, 11, 13, 17, 19, 23, 29……

As we can see in this pattern, the number in 7th position is 29.

So, he fed 29 grain pieces to the 7th bird.
