We can use the formula:
q = ne
where q is the total charge, n is the number of electrons, and e is the charge of an electron.
Given q = -7.00 µC and e = 1.60 × 10^-19 C, we can solve for n:
n = q/e = (-7.00 × 10^-6 C)/(1.60 × 10^-19 C/electron) = -4.375 × 10^13 electrons ≈ 4.38 × 10^13 electrons (since we cannot have a negative number of electrons) 
Therefore, the answer is A) 4.38 × 10^13.
