The formation of oxide layer on metals follows first order kinetics and completely stops when the oxide thickness becomes \( 10 \mathrm{~nm} \). If one hour after exposure of oxygen to metal surface the thickness is \( 7.5 \mathrm{~nm} \), then what would be the thickness 120 minute after the exposure?
(A) \( 10 \mathrm{~nm} \)
(B) \( 5.25 \mathrm{~nm} \)
(C) \( 8.475 \mathrm{~nm} \)
(D) \( 9.375 \mathrm{~nm} \)
