I believe it’s B . Not 100 percent sure but yeah
P=Ae^kt
225 = 210 * e^(k*(1990-1980)
225/210=e^10k ln(225/210)=10k
k=ln(225/210)/10=0.0069
P = 210*e^(0.0069t)
for 2000 ===> t = 2000-1980=20
P = 210*e^(0.0069*20)
P=241.0749=241
I guess maybe 5/35 because there are only 5 chances that you could get one of the 5 in the 35 people
