Detailed Solution

Given a statement, zero is the identity for addition of rational numbers.
We need to check whether the given statement is true or false.
If b is a rational number, then

b + 0 = b

. i.e., we get the same number in addition with zero.
Therefore, zero is called the additive identity of rational numbers so the statement is true.
Hence, 1 is the correct option.
