Step-by-Step Solution
Solution:
Step 1: Calculate expiration time for 7 days
7 days in seconds = 7 * 24 hours * 60 minutes * 60 seconds = 604800 seconds.Step 2: Use time() plus 7 days for expiration
The expiration parameter insetcookie()should be current time plus 604800 seconds.Step 3: Check options for correct expiration
setcookie('theme', 'dark', time() + 7 * 24 * 60 * 60); correctly usestime() + 7 * 24 * 60 * 60. setcookie('theme', 'dark', time() + 60); sets only 60 seconds, C uses 7 (invalid), D sets a past time (cookie expires immediately).Final Answer:

Quick Trick: Expire time = time() + days * 86400 seconds [OK]
