Option A.
The portion circled in red interacts with the oil while the portion circled in green interacts with the water. The green portion has alcoholic groups which can make hydrogen bonds with water. This portion is polar in nature and water also. Thus it interacts with water. Like dissolves like. The red portion is hydrocarbon chain which is non polar in nature. So it interacts with the oil which is also non polar.
