pH is the negative logarithm of the concentration of hydrogen ions (H+) in a solution. However, we are given the concentration of hydronium ions (H3O+), which is equivalent to H+ in an aqueous solution. 
The pH can be calculated using the formula: pH = -log[H3O+]. 
Substituting the given value of [H3O+] = 0.01 M, we get: 
pH = - log(0.01) = 2. Therefore, the correct answer is B, pH = 2.0.
