Explanation:

- Option 1: Expanding, reduce

- Expanding: Alternative marketing channels can help farmers access a larger market, reaching more customers.

- Reduce: By using alternative marketing channels, farmers can reduce price risk. This means stabilizing their income and minimizing the impact of fluctuating prices.

- This option is correct.

- Option 2: Reducing, Expand

- Reducing: This doesn't fit as farmers aim to expand their market.

- Expand: This is correct regarding market reach, but combined with "Reducing," the statement is incorrect overall.

- Option 3: Expand, Expand

- Expand: While alternative channels can expand market reach, they do not expand price-risk.

- Overall, this option incorrectly suggests that price risk also expands.

- Option 4: None of these

- Incorrect, as Option 1 is viable and correct.
