A solution of copper sulphate \( \left(\mathrm{CuSO}_{4}\right) \) is electrolysed for 10 minutes with a current of \( 1.5 \) amperes. The mass of copper deposited at the cathode (at. mass of \( \mathrm{Cu}=63 \mathrm{u} \) ) is
(a) \( 0.3892 \mathrm{~g} \)
(b) \( 0.2938 \mathrm{~g} \)
(c) \( 0.2398 \mathrm{~g} \)
(d) \( 0.3928 \mathrm{~g} \)
