Explanation:

- Understanding Heartwood and Sapwood:

- Heartwood: The innermost, older part of the tree that provides structural strength. It is typically darker and no longer active in water conduction. Generally more resistant to pests due to its density and often higher concentrations of protective compounds.

- Sapwood: The outer, younger part of the tree that actively conducts water and minerals from the roots to the leaves. It is less dense and thus less resistant to pests compared to heartwood.

- Statement Analysis:

- Statement 1: Incorrect; sapwood conducts water, whereas heartwood provides structural strength.

- Statement 2: Incorrect; heartwood is usually more resistant to pests than sapwood.

- Option Analysis:

- Option 1 - Only 1: Incorrect, as neither statement is correct.

- Option 2 - Only 2: Incorrect, same reason as above.

- Option 3 - Both 1 & 2: Incorrect, as both are flawed.

- Option 4 - Neither 1 nor 2: Correct, as both statements are incorrect.

- The correct answer is Neither 1 nor 2 from Option 4.
