Solution

The correct option is D 200
The projection of population growth in yeast is given by
$N = N_{O} e^{r t}$
Where e = national logarithmic base = 2.72, $N_{o}$ = initial population, r = intrinsic rate of natural increase (0.5 for yeast), t = time.
N = $10 \times {2.72}^{(0.5 \times 6)}$
Hence, N = 200.86, i.e., after 6 hours, the population is expected to have about 200 individuals.
Therefore, the correct answer is option D.
