Choose the word that is opposite in meaning to the given word.
CONVEX

a) flat
b) protuberant
c) full
d) indented

Answer 1

Hint: Antonyms are those words that express a meaning opposed to the meaning of another word, in which case the two words are antonyms of each other.

In the given question, the word ‘convex’ refers to something or someone curving or bulging outward.

Complete answer:

Let us analyze the options given to us in this question:
Option (a.), 'flat', refers to something having a surface without slope, tilt in which no part is higher or lower than another.
Therefore, option (a.) is incorrect as its meaning is not antonymous to that of the given word ‘convex’.

Option (b.), ‘protuberant', refers to something curving outward.
Therefore, option (b.) is incorrect as its meaning is not antonymous to that of the given word ‘convex’.

Option (c.), ‘full', refers to constituting the full quantity or extent; complete.
Therefore, option (c.) is incorrect as its meaning is not antonymous to that of the given word ‘convex’.

Option (d.), ‘indented', refers to ‘make a depression into; dented’.
Therefore, option (d.) is correct as its meaning is antonymous to that of the given word ‘convex’.

Note: Sometimes the given options in a question where we have to find the opposite of the given word do not exactly mean the opposite of the given word. If this happens, we have to select the option which is the most anonymous to the meaning of the word in the question. Some antonyms of the given word ‘convex’ are- concave, recessed, indented.
