Explanation:
Scarcity occurs when our want and the needs are more than the available resources that we have. In this case, we will then have to make a choice to be able to choose from the different alternatives that we have.
When we make a choice, the cost of the other alternative that we left is refered to as the opportunity cost. Therefore, the correct options are:
• The "highest-valued alternative given up to get something" is the opportunity cost.
• Scarcity creates opportunity costs

Arousal is spread through the Sympathetic Nervous System, with impacts, for example, expanding the pulse and breathing to empower physical activity and sweat to cool the body. It likewise has particular activities, for example, stimulating sexual arousal.
