Question

Select the most appropriate one-word substitution for the given description:
That which cannot be defeated. ___________.
A) Invincible
B) Incredible
C) Incomparable
D) None of these

Answer 1

Hint: The use of a single word in place of a long-phrase to make the sentence structure simpler is known as one-word substitution. With the phrase replaced, the meaning remains the same while the statement becomes shorter. A single word must be substituted for a sentence in a One Word Substitution question.

Complete answer:
Let us analyze the given options now:
Option A) Invincible: Invincible signifies -A seemingly unstoppable army is incapable of being defeated, overcome, or subdued. Invincible, impregnable, and indomitable all refer to something that can't be defeated or mastered. An invincible army; invincible courage are examples of things that cannot be defeated in battle or war or overcome or subdued in any way. The term "invincible" refers to anyone who cannot be defeated. So, the one-word substitution of ‘That which cannot be defeated’ is invincible. Hence, this option is correct.
Option B) Incredible: The word 'incredible' means 'difficult or hard to believe.' Which can not substitute ‘That which cannot be defeated’ in one word. Hence, this option is incorrect.
Option C) Incomparable: The term 'incomparable' refers to something that cannot be measured or matched. Which can not substitute ‘That which cannot be defeated’ in one word. Hence, this option is incorrect.
Option D) None of these: We already know that Option A. is the correct answer. Hence, this option is incorrect.

Therefore, Option ‘A’ i.e, Invincible is the correct answer because it describes ‘That which cannot be defeated’.
