Carnoy's solution is composed of acetic acid, chloroform, and which alcohol?

Explanation:
Carnoy's solution is a rapid fixative made from acetic acid, chloroform, and an alcohol. The alcohol used is absolute ethyl alcohol, meaning ethanol that is anhydrous. Using absolute ethanol provides swift dehydration and protein precipitation, helping to fix tissues quickly and preserve nuclear detail. The other ingredients support penetration and clearing (chloroform) and enhance nuclear preservation (acetic acid). Using a different alcohol would change the fixation characteristics, so the correct component is absolute ethyl alcohol.
