Answer
Correct option: A.
which stabilises an emulsion.
An emulsifier is a substance that acts as a stabilizer in an emulsion and prevents the mixing of two solutions.
An emulsifier has a water$-$loving hydrophilic head and an oil$-$loving hydrophobic tail.
The hydrophilic head is for the aqueous phase and the hydrophobic tail is for the oil phase.
