Option 1 -> Ignoring the problem would mean taking no action, which doesn't align with seeking justice for false claims.
Option 2 -> Writing a social media review is informal and doesn't provide legal recourse for the issue.
Option 3 -> Filing a complaint with the Consumer Forum is a formal legal action to address false claims and seek redress.
Option 4 -> Simply returning the product doesn't address the broader issue of false advertising or hold the company accountable.
Hence, Option 3: Filed a complaint with the Consumer Forum -> This is the appropriate legal action when a consumer discovers false claims about a product, as the Consumer Forum provides a formal mechanism to seek justice and hold businesses accountable for misleading information -> correct
