Answer Options

Correct Answer A. A_0\left\( \frac{1}{2}\right \)^{t/t_{1/2}}
B. A_0\left\( \frac{1}{2}\right \)^{t_{1/2}/t}
C. A_0\left\( \frac{1}{2}\right \)^{t/t_{1/2}}+A_0
D. A_0\left\( \frac{1}{2}\right \)^{t/t_{1/2}}-A_0
Correct Answer
A
Correct Option:
A_0\left\( \frac{1}{2}\right \)^{t/t_{1/2}}
