What is the common trade name for the red dye derived from cochineal scale insects?

Explanation:
This question tests your recognition of the trade name for the natural red dye derived from cochineal insects. The pigment you’re looking for is carmine, which is produced by crushing the bodies of female cochineal scale insects (primarily Dactylopius coccus). Carmine gives a bright, stable red color and is widely used as a natural food colorant and cosmetic pigment. In labeling, you’ll often see it called carmine or natural red 4 (known as E120 in some regions). The other terms aren’t standard trade names for this specific dye, and they don’t uniquely identify the pigment derived from cochineal insects.
