The correct answer is option A.

Explanation:

Internal validity is a concept to tell the validity of the statistical analysis, the extent to which it supports the cause and effect relationship.

Inferences here are applicable only on the population on which study is based.

If the inferences can be generalized then we say external validity is there.

Also, for internal validity the estimator of the causal effect should be unbiased and consistent.
