What is a race condition in operating systems ?
Answer: B
A race condition is multiple processes accessing shared data concurrently, so that the result depends on the timing.
If two threads both read a counter, add one and write it back, their steps can interleave so that one update is lost, and the final value depends on which ran first. Code that touches shared data must be a critical section protected by mutual exclusion, with locks, semaphores or atomic operations.
Competition for the CPU is handled by the scheduler and is not a race condition. Waiting for I/O is ordinary blocking. Priority inversion is a different scheduling problem, where a high-priority task waits on a lower-priority one.
