To find the percent by mass of chlorine, we need to calculate the total mass of the compound first.

mass of compound = mass of iron + mass of chlorine
mass of compound = 1.37g + 2.62g
mass of compound = 4.00g

Now, we can calculate the percent by mass of chlorine:

% chlorine = (mass of chlorine / mass of compound) x 100%
% chlorine = (2.62g / 4.00g) x 100%
% chlorine = 65.5%

Therefore, the answer is B) 65.7%.
