Select the option that will improve the highlighted part of the given sentence. In case no improvement is needed, select 'No improvement required'.
After all the fuss, the companies has still not reach a consensus.

Correct option is A

The correct substitution of the highlighted part is (a) have still not reached.
Explanation:
· The subject "companies" is plural, so the verb should be in plural form as well.
· "Has" is singular, but "companies" require the plural auxiliary verb "have."
· The verb "reach" should be in past participle form ("reached") because the correct tense structure is present perfect ("have + past participle").
Corrected sentence:
"After all the fuss, the companies have still not reached a consensus."
Grammatical Rule Used:
· Subject-Verb Agreement: Singular subjects take singular verbs, and plural subjects take plural verbs.
· Present Perfect Tense: has/have + past participle is used to indicate actions completed at an indefinite time.
Example:
· Incorrect: The students has completed their work.
· Correct: The students have completed their work.
Why other options are incorrect:
· (b) have still to reached – Incorrect because "to" should be followed by the base form of the verb ("reach," not "reached").
· (c) had still not reach – Incorrect because "had" requires "reached" (past participle), not "reach." Also, "had" suggests past perfect tense, which is not needed here.
· (d) No improvement required – Incorrect because "has" should be "have," and "reach" should be "reached."
