Answer 1

Hint: A verb is a content word that denotes an action, occurrence, or state of existence.
It is the word class that serves as the predicate of a sentence.
For example- ‘said’, ‘sleep’, ‘drink’.

Complete answer:
In the given question, the verb ‘doubling’ in the second sentence indicates that the population became more very fast.
Let us analyze the options given to us in this question:
Option (a.), 'is rising', refers to advancing or becoming higher or greater in degree or value or status;
Therefore, option (a.) is correct as it indicates that the value of the population is more than before.

Option (b.), ‘is increasing', refers to a quantity that is added; a process of becoming larger or longer or more numerous or more important.
Therefore, option (b.) is correct as it indicates that the value of the population is more than before.

Option (c.), ‘is changing', refers to making something or someone different; causing a transformation.
Therefore, option (c.) is incorrect as it does not indicate that something’s value is becoming more.

Option (d.), ‘is getting', refers to the act of acquiring something.
Therefore, option (d.) is incorrect as it does not indicate that something’s value is becoming more.

Both the options are correct (option a and b) as this question has multiple correct answers.

Note:
 In this question, do not confuse ‘is changing’ to be the right answer. According to the sentence, the population is changing, however, it is growing, as is indicated by the verb ‘doubling’. This is why the options ‘is increasing’ and ‘is rising’ are more appropriate since they indicate the specific direction of growth.
