i really need help this packet is due tomorrow.! Which equation defines p as a function of t?

Answer:
B
Step-by-step explanation:
B for the first one. We have to eliminate A and C right away because they are asking for a function of t and not p. So, in that case it has to start with p. I didnt choose D because there is no such thing as 0p it is 1p. So I am pretty sure its B for the first one.
