Answer:

Option C, 0.20 – 0.10 = 0.10

Explanation:

Total number of births taking place in an year is equal to 200.

Number of births per person is equal to

\frac{200}{1000} = 0.2

Total number of deaths happening in an year is equal to 100

Number of deaths per person is equal to

\frac{100}{1000} = 0.1

Net growth in population per person

Total number of births per person - total number of deaths per person

Substituting the given values in above equation, we get -

0.20 -0.10 = 0.10

Hence, option C is correct
