A quick quiz

The sentence should mean: “If you don’t eat it quickly, the ramen will get cold.” As it is the ramen that would cool down by itself, not a person trying to cool it down, we need to use an intransitive verb that means “to lose heat,” which is c. 冷さめ. a. 冷ひえ is also an intransitive verb but that means “to get chilled (in a fridge or so)” so it does not suit the context.

If you are not sure about the difference between transitive verbs and intransitive verbs, watch this video and/or do some exercises with Transitive verbs vs Intransitive verbs module.

By the way, in summer, many people in Japan like to eat chilled Chinese style noodles called 冷麺れいめん or 冷ひやし中華ちゅうか. The word 冷麺れいめん is pronounced like レーメン which makes a slight pun with ラーメン that is always served hot.
