Solution

The correct option is A three
Hydroxyl group makes the alcohol molecule polar and these are used as protic solvents. Two opposing solubility trends in alcohols are the tendency of the polar OH to promote solubility in water and the tendency of the carbon chain to resist it. So, methanol, ethanol, propanol are miscible in water as the OH group overcomes the short carbon chain.
