Answer:
C). Parallel forms reliability.
Explanation:
'Parallel forms reliability' is exemplified as the method that intends to test or measure the reliability of an experiment through varied evaluation tools like similarity of skill, construct, or knowledge among the individuals belonging to the same group.
In the given experiment, the two different evaluation tests are being conducted to test the reliability and 'how intimately they are correlated'. Thus, the results could be considered reliable as the results have been cross-examined by testing them twice and result remaining the same.Thus, it exemplify 'parallel forms reliability' i.e. option C is the correct answer.
