Solution

I never listen to the radio.

✅ Correct preposition: "to"

Explanation:

When we use the verb "listen", it is typically followed by "to" when referring to something we are paying attention to or hearing, like music, a broadcast, or the radio.

Examples:

• I like to listen to music in the evening.

• She listens to the news every morning.

Solution

The verb "conform" is typically followed by the preposition "to" when you're talking about obeying or aligning with rules, standards, or expectations.

Examples:

• All employees must conform to the company policies.

• His actions do not conform to our standards.

Solution

We use "at" when referring to a specific point or location—and "the campus" in this sentence is considered a specific place.

Let’s break it down:

• "at" = specific location
  ➤ "He's waiting at the bus stop."
  ➤ "She's studying at the library."
  ➤ "We're meeting at the restaurant."

• "on" = surface
  ➤ "The book is on the table."

• "in" = inside an enclosed space
  ➤ "He's in the building."
  ➤ (You might say "in the campus" if you’re thinking about being within the grounds of a large university, but "at the campus" is more natural when referring to meeting someone there.)

So: ✅ "Jagdish is waiting for me at the campus."
is correct because it's talking about a meeting point or location.
