To add 1 to the $count variable, you can use the following options:

a. $count =+1: This is not the correct way to add 1 to the$count variable. The correct syntax is $count += 1.

b. ++$count: This is the correct way to add 1 to the$count variable. The prefix increment operator (++$count) increases the value of$count by 1 before using it in any expression.

c. $count++: This is also a correct way to add 1 to the$count variable. The postfix increment operator ($count++) increases the value of$count by 1 after using it in any expression.

d. count++: This is not the correct way to add 1 to the $count variable. The correct syntax is$count++ or ++$count.

So, the correct options to add 1 to the $count variable are b. ++$count and c. $count++.
