Thread one holds myLock1 and is waiting for myLock2, while thread two holds myLock2 and is waiting for myLock1. This creates a circular wait and leads to a deadlock. Neither thread can proceed until the other releases the lock it is waiting for. Therefore, the correct answer is C - deadlock will occur.
