Question

That which cannot be corrected
A) Incorrigible
B) Illegible
C) Illegal
D) Indelible

Answer 1

incorrigible cannot be corrected

Answer 2

Illegal means disobeying by law or doing some kind of unfair activities against the existing law.

indelible means not able to be forgotten.

Illegible means not clear enough to be read.

We can see all the above three words have a different set of meaning.

Incorrigible is the word that has the meaning not able to be corrected or changed, so option A) Incorrigible is the correct answer.
