Using the graph of $3 + \cos(5 x)$, for $0\le x\le \frac{3\pi}{5}$, list the following quantities in increasing order:
A. the value of the integral $\displaystyle \int_0^{\frac{3\pi}{5}} (3 + \cos(5 x)) \, dx$,

B. the left sum with $n = 3$ subdivisions, and

C. the right sum with $n = 3$ subdivisions.

(Enter the letter of the value in each box.)
