Select the most appropriate option to fill in the blank.
The detail given by the instructor was the ______ one.

Correct option is A

The correct option to fill in the blank is (a) most updated.
Explanation:
The superlative degree is required here to match the article "the" and the singular noun "one." Hence, "most updated" is appropriate. It implies that among many details, this one was the latest.
(Hindi meaning: सबसे अद्यतन/नई जानकारी)
Example: This is the most updated version of the report.
Incorrect options:
· (b) updates – plural noun; not suitable for “the ___ one”.
· (c) more updation – ungrammatical and awkward usage.
· (d) updating – present participle, not suitable in this context.
