Assertion:
The problem solving ability, mental performance and memory of the employees of company C are deteriorating.
RI. Due to tight schedule at company C, the employees of the company are skipping their breakfast regularly.
RII. The job is physical in nature, but not mental.
Answer: D
Here in the assertion, we are only talking about the weakness of the employees. RI is giving the reason for skipping breakfast, so it is not the reason. RII is also not a valid reason, as lack of mental exercise may not lead to deterioration.
