Select the most appropriate option to fill in the blank.
This app is a very ______ one for online shopping.

Correct option is A

The correct option to fill in the blank is (a) convenient.
‘Convenient’ is an adjective, and here it is used to describe the app, which is a noun. We need an adjective to qualify the noun.
Example: This tool is very convenient for editing documents.
Explanation:
• ‘Convenient’ = suitable, easy to use, or comfortable. (Hindi: सुविधाजनक)
• The structure of the sentence needs: “This app is a very + adjective + one...”
Meanings of other given words and why they are incorrect:
· (b) convenience – noun; not suitable here where an adjective is required (सुविधा)
· (c) capable – adjective but refers to ability, not suitability (सक्षम)
· (d) competency – noun meaning skill or ability (क्षमता)
