Select the most appropriate option to fill in the blank.
The people of our country have full confidence in the ______ of its defense forces.

Correct option is B

The correct option to fill in the blank is (b) capabilities.
Explanation: The word capabilities means “the power or ability to do something effectively.” (Hindi meaning – क्षमता, योग्यता).
So, the sentence means that people trust the abilities of the defense forces.
Example: Our army has great capabilities in mountain warfare.
Why other options are incorrect:
· (a) Susceptibilities – The state of being easily affected (संवेदनशीलता, असर में आने की प्रवृत्ति).
· (c) Facilities – Amenities or services (सुविधाएँ).
· (d) Sensibilities – Capacity to feel or perceive (संवेदनशीलता, भावुकता).
Hence, “capabilities” fits both grammatically and contextually.
