Answer: Option (A) is correct.

Explanation:

In accordance with the split-half reliability, a study or test for a particular knowledge domain is divided into 2 parts and therefore both parts are given to a single group of individuals at a particular time. The scores received from these parts of test are somewhat correlated.

Split-half is known as an evaluation of consistency (internal) i. e. how well do components tend to contribute to variables which are being measured.
