Which of the following statements is true about race conditions in real-time embedded systems?

Race conditions occur when software behavior depends on the timing or sequence of events, such as task scheduling, interrupts, shared resource access, or concurrent execution. In real-time embedded systems, race conditions can be difficult to reproduce because they may occur only under specific timing, load, or concurrency conditions. They can occur in multi-processing and multi-threaded systems, especially when synchronization is weak. Stress testing is useful because it places the system under high load, timing pressure, rapid event sequences, or resource contention, increasing the likelihood of exposing race conditions. Unit testing may find some logic defects, but many race conditions require integrated timing and concurrency conditions. Therefore, stress testing is the best answer.
