An "Up" Quark Has a Charge Of $-2 / 3$ Times the Electron's Charge

An "up" quark has a charge of $-2 / 3$ times the electron's charge. A "strange" quark has a charge of $+1 / 3$ times the electron's charge. What is the net charge of the quark triplet consisting of two up quarks and a strange quark? (This quark triplet is one of a family of three " $\Sigma$ particles.")

A) $+(5 / 3) e$
B) $+e$
C) $+(1 / 3) e$
D) zero
E) $-(1 / 3) e$
F) -e
G) -(5/3) e
