Solution

The correct option is A
K=2.303tlog[A]0[A]t

For the first reaction, A Products, the integrated rate law is given by the equation.

K=2.303tlog[A]0[A]t

where,
[A]0 is the initial concentration of the reactant at t=0

[A]t is the concentration of the reactant at t = t.

So, the correct option is A.
