What are the dimensions of the basic magnitudes in the International System of Units (SI)?

I- Length, mass, time, electric current, temperature, amount of substance, and luminous intensity are the basic dimensions of the SI.
II- The derived coherent units expressed from the basic units are area, volume, speed, acceleration, and density.
III- The derived coherent units with special names and symbols are frequency, force, pressure, energy, power, electric charge, potential difference, electric resistance, electric conductance, magnetic flux, magnetic flux density, inductance, Celsius temperature, absorbed dose, equivalent dose, and activity of a radionuclide.
IV- The derived coherent units with names and symbols that contain derived SI units with special names and symbols are dynamic viscosity, moment of force, surface tension, angular velocity, angular acceleration, thermal capacity, specific heat capacity, energy density, electric field strength, electric charge density, electric flux density, permittivity, permeability, molar energy, molar entropy, and exposure.
a) Only I and II are correct.
b) Only II and III are correct.
c) Only III and IV are correct.
d) All statements are correct.
