Assertion(A): Congenital diseases are not communicable.
Reason(R): Congenital diseases are caused by microorganisms.
Correct answer: (c) Assertion(A) is true and reason(R) is false.
Congenital diseases are not communicable because these are inherited at the time of birth and cannot be spread from person to person.
No external agents like microbes are involved in the development of these diseases.
They mostly develop due to genetic disorders.
So, the assertion is true, but the reason is false.
