Choose the best option to correct the highlighted word in the following sentence.
The video conference allowed team members to work simultaneities across different time zones.

Correct option is B

The correct substitution of the highlighted word is (b) simultaneously.
Explanation:
The verb work needs an adverb to describe how the team members worked. Simultaneously is an adverb meaning at the same time. (एक साथ, एक ही समय पर)
The corrected sentence is:
The video conference allowed team members to work simultaneously across different time zones.
Grammatical Rule Used:
An adverb modifies a verb, adjective, or another adverb. Since work is a verb, it must be modified by the adverb simultaneously, not by a noun or adjective.
Example:
· The dancers performed simultaneously.
· The students answered the questions simultaneously.
Why other options are incorrect:
· (a) simultaneousness: A noun meaning the quality of being simultaneous. It cannot modify the verb work.
· (c) simultaneous: An adjective meaning occurring at the same time. An adjective cannot modify the verb work.
· (d) simultaneity: A noun meaning the state of occurring together. It is not suitable after the verb.
Information Booster:
Words ending in -ly are generally adverbs.
· Quick → Quickly
· Careful → Carefully
· Simultaneous → Simultaneously
