Calculation:

Let the present value be P.

Then future value will be 3P.

Write the expression to calculate the future value.

$F=P{(1+i)}^{n}$ .......(I)

Here, the future value is F, the present value is P, the rate of interest is i and the time period is n.

Substitute P for P, 3P for F and 0.08 for i in Equation (I).

$3P=P{(1+0.08)}^{n}$

$3={\left(1.08\right)}^{n}$

Solve for the value of n.

$n=14.27$ years.

Conclusion:

Thus, the correct answer is option (b) 14.27 years.
