Calculation:

To calculate the death rate, we need to divide the number of deaths by the number of individuals at the beginning of the interval.

Let's use the formula for death rate:

Death Rate = Number of Deaths / Number of Individuals at the Beginning of the Interval

Given in the question:

Number of individuals at the beginning of the 1st year to 2nd year interval = 800
Number of deaths during this interval = 200

Substituting the values:

Death Rate = 200 / 800

Simplifying the above expression, we get:

Death Rate = 1/4 = 0.25

Therefore, the death rate for this interval is 0.25.

Explanation:

The death rate is a measure of the number of deaths in a population relative to the total population. It tells us the proportion of individuals who die during a specific time interval.

In this case, we are given the number of individuals at the beginning of the 1st year to 2nd year interval, which is 800. We are also given the number of deaths during this interval, which is 200.

To calculate the death rate, we divide the number of deaths by the number of individuals at the beginning of the interval. This gives us the proportion of individuals who died during the interval.

Substituting the given values into the formula, we find that the death rate is 0.25.

Therefore, the correct answer is option 'A' - 0.25.
