Explanation:

The obtaining resources phase of a product's life cycle involves getting the raw materials. In this case, ethylene (a key component for making polyethylene) is produced from petroleum, which is extracted from the earth. This directly relates to obtaining resources.

• Option A is about the distribution phase (sending to markets).
• Option B is about the recycling phase (collecting, cleaning, shredding used jugs).
• Option C is about the manufacturing phase (making ethylene into polyethylene and molding into jugs).

Answer:

D. Ethylene is produced from petroleum, which is extracted from the earth.
