Choose the odd one out from the following?

Let's analyze each option:

Option (a): Curd – A dairy product made from milk.

Option (b): Cheese – A dairy product made from milk.

Option (c): Milk – A natural dairy product.

Option (d): Alcohol – A fermented beverage, not a dairy product.

Curd, Cheese and Milk are dairy products.

So, Alcohol is not related to dairy. Alcohol is odd one.

Thus, correct option is (d).
