Option A uses a conditional statement to check if the current year is 2020 and then sets the value in the dayCount array for February to 29. This is the correct way to ensure February has 29 days only in a leap year.

Option B is incorrect as it sets the year value to 2020 instead of the value in the dayCount array.

Option C is incorrect as it does not use the correct syntax for conditional statements and is missing the parentheses after the keyword "if".

Option D is incorrect as it uses a single "=" instead of "==". Additionally, the conditional statement is not properly enclosed in parentheses and the order of the conditions is incorrect.
