Question

Choose the word which best expresses the meaning of the underlined word in the sentence:
Decay is an immutable factor of human life.
A)important
B)unique
C)unchangeable
D)awful

Answer 1

Hint: Immutable is an adjective, which means something that is inflexible and cannot be changed.

Complete step-by-step answer:

From the hint given to us, we know that immutable is an adjective, which means something that is inflexible and cannot be changed. The word which expresses the meaning of immutable the best must have a similar meaning.
Important means being significant and relevant. It is an adjective. We observe that the meaning of importance is not the same as that of immutable. Hence, option A is not the correct answer.
Unique means one of a kind and not similar to anything else. It is an adjective. We observe that the meaning of unique is not the same as that of immutable. Hence, option B is not the correct answer.
Unchangeable means inflexible and something that cannot be changed. It is an adjective. We observe that the meaning of unchangeable is the same as that of immutable. Hence, option C is possibly the correct answer.
Awful means are very bad and distasteful. It is an adjective. We observe that the meaning of awful is not the same as that of immutable. Hence, option D is not the correct answer.
After observing all the given options and analyzing them, we can conclude that option C is the correct answer.

Note: Immutable is more formal for unchanging. Unchanging is more of a common word.
