An interactive satellite-based distance education system for the country…

Correct answer: EDUSAT

Why this is correct:

• EDUSAT is a satellite system dedicated to educational services, designed to deliver audiovisual content to educational institutions across the country.

• It supports interactive distance education features such as teleconferencing, one-to-many video delivery, and two-way audio in many configurations.

• Because it is specifically intended for nationwide educational use and supports audiovisual interactivity, it matches the description in the question.

Why the other choices are not correct:

• Community Radio (FM) is audio-only and serves local community areas; it is not a nationwide interactive satellite-based audiovisual system.

• CLASS (as presented) is not the dedicated educational satellite infrastructure described and does not denote the national interactive audiovisual satellite system.

• DTH (Direct-To-Home) delivers television channels directly to homes and is typically one-way commercial broadcasting, not the dedicated interactive educational satellite service the question describes.

Extra context: EDUSAT was launched by ISRO specifically to support distance learning and tele-education, making it the appropriate match for the described interactive satellite-based audiovisual distance education system.
