Answer:

Correct choice is D

Explanation:

Consider the exponential function
$R=10.5\cdot (0.535)^t.$

The exponential function of exponential decay can be written as

$y=a\cdot (1-r)^x,$

where r is the decay rate.

Note that 1-0.535=0.465. The decimal 0.465 is 46.5% and this percent represents the rate of exponential decay.
