B) programmers don't need to worry about race conditions.

C) a thread cannot block inside a critical section.

D) deadlock cannot occur.

Answer:

A. Management of entry and exit code is managed by OpenMP library reducing the possibility of programming errors

Step-by-step explanation:

This is a multiple choice question and this is the answer because:

1. OpenMp is inclusive of an APL/compiler directives:

2. any code which follows #pragma omp parallel is a parallel region and it is performed by large number of threads that are same as the number of processing cores that are in the system.

3. The critical-section compiler directive acts more like a binary semaphore or mutex lock,it makes sure that only one thread is active in the critical section at the same time.
