I believe it’s the first one. i’m very sorry if it’s wrong
Formula- A = π r²
a= area
r= radius
diameter of the circle- 3.75 x 2 = 7.5

I’m assuming a. Or 26 since it’s the only number within the range
I don't know if this helps but an equivalent rate is:Rates that represent the same comparison; for example 90km
2h Fraction<------
and 45km/h Confusing i know
