The correct answer is option c - Methanal.
Methanal is the systematic name of Formaldehyde (CH2O). Methanal (formaldehyde) is also known as formalin (40% formaldehyde)
Methanal (formaldehyde) is usually used as an aqueous solution containing 37% (w/w) methanal, known as formalin. It contains a small amount of methanol and an inhibitor (often an ethenyl (vinyl) polymer) to prevent the aldehyde from forming long chain polymers on storage.
Methanal is usually added to biological specimens to suppress oxidation and polymerization which helps in preserving them for a long time. Usually, 3-5% Formalin is used in jars in which most animal specimens or herbaria are preserved.
