From the paragraph, we can extract the following information:
P = Principal Amount = given as $200
t = time = given as 4 years
r = interest rate = Given as 2.8%
I = interest = $22.40
Compare the 4 choices with the givens above:
r = 2.8% (consistent with above, True)
t = 200 (not consistent with above, False)
p = 4 (not consistent with above, False)
I = $22.40 (Consistent with above, True)
