Correct Answer: Option C

Explanation

In the case of joint supply, an increase in the demand for one commodity (X) will lead to an increase in the supply of the other
commodity (Y). This is because both commodities are produced together, so if more of one is produced, more of the other will also
be produced. This concept is known as joint supply.
