During the study of kinetics of chemical or nuclear reaction, `t_(1//3)` can be defined as

Options

A. A. One-third of the reaction molecules are left.
B. B. Two-third of the reaction molecules are left.
C. C. One-third of half of the reaction molecules are left.
D. D. One-third of two-thirds of the reaction molecules are left.
