Explanation:

- Statement 1: "A jet engine uses the surrounding air for its oxygen supply and so is unsuitable for motion in space."

- This is correct. Jet engines need air from the atmosphere for combustion, so they can't work in space where there is no air.

- Statement 2: "A rocket carries its own supply of oxygen in the gas form, and fuel."

- This is only partially correct. Rockets do carry both fuel and an oxidizer, but the oxidizer is not always in gaseous form (it can be liquid or solid).

- Options:

- Option 1: 1 only – Only statement 1 is correct.

- Option 2: 2 only – Only statement 2 is correct.

- Option 3: Both 1 and 2 – Both statements are correct.

- Option 4: Neither 1 nor 2 – Neither is correct.

Correct Answer:

Option 1: 1 only
