(Choose only one answer) A solution to the Readers-Writers problem is given below. Which of the following statements is TRUE? int reader=0; semaphore read_mutex=1, data_mutex=1; process reader() { while (true) p(read_mutex); reader=reader+1; if (reader=-1) p(data_mutex): v(read_mutex); -- read data p(read_mutex); reader=reader-1; if (reader==0) v(data_mutex); v(read_mutex); 1 ) process writer() { while (true)! -- execute p(data_mutex); -- write data v (data_mutex); 1 Select one: O A. Indefinite postponement may occur. O B. data_mutex should have been initialized to O instead of 1 O C. Deadlock may occur O D. Semaphores are used for synchronization in this solution
