A statement followed by two assumptions are given below. Select the assumption(s) from the options which is implicit in the statement.
Select
(A) If only assumption (i) is implicit
(B) If only assumption (ii) is implicit
(C) If both (i) and (ii) are implicit
(D) If neither (i) nor (ii) is implicit
Statement:

Detergents should be used to clean clothes
Assumptions:
i) Detergents form more lather
ii) Detergents help to dislodge grease and dirt ​​

Detergents should be used to clean clothes
Assumptions:
i) Detergents form more lather.  Not implicit.

The statement doesn't mention or depend on lather formation.

ii) Detergents help to dislodge grease and dirt. Implicit.

This directly supports the reason why detergents should be used to clean clothes.​

So, If only assumption (ii) is implicit

Thus, the correct option is: (b)
