Suppоse wireless nоdes A аnd C аre hidden terminаls оf each other. Node B is within their common sensing/transmission range, and node D is only within C’s range. There may be other nodes nearby. Suppose the data transmission (neglecting the propagation delay) takes 10 time slots, and an RTS/CTS/ACK transmission only takes 1 time slot. Please answer the following questions:  1). A sent its data to B at t=0 (time slot). At t=2, C has data to send to B. If MACA is not used, C can send its data at t=[BLANK-1], which leads to a [BLANK-2] (fill A or B). This is called the [BLANK-3] (fill C or D) terminal problem.  A. collision B. delay C. exposed D. hidden 2). Suppose MACA is used between A and B. Then, for the same situation, A will send an RTS at t=[BLANK-4]. In this case, C will send its RTS until t=[BLANK-5].  3). The [BLANK-6] (fill A or B) terminal problem can be entirely solved by the MACA mechanism while the other one still has a certain scenario that cannot be solved. A. exposed B. hidden
