Consider the following two statements and choose the correct option:

1.The experimental group is the group of research participants who receive the experimental treatment

2.True experiments must have at least one control group, though it is possible to have more than one experimental group

AOnly 1 is true

BOnly 2 is true

CBoth 1 and 2 are true ✓ Correct

DNeither 1 nor 2 is true

Correct answer: (C) Both 1 and 2 are true

Explanation

Both statements are true about experimental groups.

The experimental group is the set of participants who receive the treatment.

A true experiment needs at least one control group.

It may, however, contain more than one experimental group.

Neither statement is false, so any single-statement choice would be incomplete.

Random assignment distributes participants across these groups.
