Question

Is there any good show .......... television tonight?

• A. in
• B. at
• C. within
• D. on

Hint:

For media like television and radio, always use "on" to refer to broadcasts (e.g., "on TV", "on the radio").

Answer 1

The Correct Option is D

Correct Usage: The phrase "on television" is the standard expression when referring to television programs or broadcasts. The preposition "on" is used to indicate something that is being broadcast or shown through media such as television. 
Why Other Prepositions Are Incorrect:

• "In television" would imply being physically inside a television, which is illogical.
• "At television" is not a standard construction in English. We might say "at the television" (referring to the device) but not "at television".
• "Within television" suggests being inside a medium, which doesn’t fit the context of watching shows.

Conclusion: The correct preposition to use in this context is "on".
