To find the correct answer, let's examine the options given.

a) Two years
b) Four years
c) Five years
d) Six years

The question asks about the average time difference between when girls and boys start puberty. Puberty typically begins between the ages of 9 and 14, but there is variation between individuals.

To determine the correct answer, we need to find out who typically begins puberty earlier, girls or boys. In general, girls tend to start puberty earlier than boys. On average, girls start puberty around the age of 10-11, while boys usually begin around the age of 12-13.

Looking at the options, we see that option a) "Two years" suggests that girls begin puberty two years ahead of boys. This aligns with the general understanding that girls start puberty earlier. Therefore, the correct answer is indeed option a) "Two years."
