Answer:
B. As a professor of Molecular Biology, Alex needs to prepare for class, write to apply for research fund, design research projects and attend conference.
Step-by-step explanation:
Role strain refers to a conflict that occurs within one role while having numerous statuses. This is different from role conflict, which occurs when having two roles, for example being a student and an employee at the same time.
In this scenario, Alex has one single role: Molecular Biology Professor. However, he has a role strain: having to prepare for many tasks: prepare his class, apply for funding, designing research projects, and at the same time, preparing to attend a conference. This means that he has a conflict with his single role because he has numerous statuses or tasks.
Therefore, the correct answer would be B.
