Assertion: There is a two-way relationship between disability and poverty. 
Reason: Malnutrition, mothers weakened by frequent childbirth, inadequate immunisation programmes, and accidents in overcrowded homes all contribute to a higher incidence of disability among poor people.

Both A and R are true but R is not the correct explanation of A

The correct answer is Option 2: Both A and R are true but R is not the correct explanation of A

Assertion (A): There is a two-way relationship between disability and poverty. True because poverty increases the risk of disability through poor nutrition, inadequate healthcare and unsafe living conditions. At the same time, disability also creates and worsens poverty by increasing isolation and economic strain for the individual as well as the family, making disabled people among the poorest in poor countries.

Reason (R): Malnutrition, mothers weakened by frequent childbirth, inadequate immunisation programmes, and accidents in overcrowded homes all contribute to a higher incidence of disability among poor people. True because these conditions explain how poverty contributes to a higher incidence of disability among poor people.

However, (R) is not the correct explanation of (A). The Reason explains only one direction of the relationship—that poverty leads to disability. It does not explain the other direction, namely that disability also creates and exacerbates poverty by increasing isolation and economic strain for the individual and the family. Hence, the Reason does not fully explain the Assertion.
