Question

1. reading the owners manual, using the product as intended, and keeping the receipt are ways to...

protect and maintain your purchase
go into debt over an item
think through a purchase
avoid regretting an impulse purchase

Explanation:

• "Go into debt over an item" is incorrect as the actions (reading manual, using as intended, keeping receipt) don't relate to debt.
• "Think through a purchase" is about decision - making before buying, while the actions here are post - purchase.
• "Avoid regretting an impulse purchase" is also about post - impulse - buy regret, but the actions are more about protecting and maintaining the purchased item.
• "Protect and maintain your purchase" makes sense: reading the manual helps use it correctly, using as intended prevents damage, and keeping the receipt helps with returns/warranties, all to protect and maintain the purchase.

Answer:

A. Protect and maintain your purchase
