• A. Visible mold on the surface
• B. Fresh aroma
• C. Firm texture
• D. Bright color

Answer: (A)

Visible mold on the surface is a strong sign that stored food might be unsafe to eat. Mold indicates microbial growth that can produce toxins, and those toxins can spread through the food even if you can’t see it everywhere. Once you see mold, the safest move is to discard the item rather than try to trim it away or cook it off, because safety can’t be guaranteed. For context, mold can appear on bread, fruit, dairy, and many other foods, and it often means spoilage has begun.

A fresh aroma isn’t a reliable warning sign of danger; it usually suggests the food is still okay, though spoilage can sometimes occur without a strong smell. A firm texture can indicate the food hasn’t begun to spoil, and a bright color can occur for legitimate reasons as well, so these signs aren’t dependable indicators of safety on their own.
