Kiran’s family is having people over to watch a football game. They plan to serve sparkling water and pretzels. Each person will be served 12 ounces of sparkling water and 3 ounces of pretzels. Including Kiran’s family, there will be 10 people at the gathering.

- A bottle of sparkling water contains 22 ounces and costs $1.50.
- A package of pretzels contains 16 ounces and costs $2.99.

Let:
- \( n \) represent the number of people watching the football game,
- \( s \) represent the ounces of sparkling water,
- \( p \) represent the ounces of pretzels,
- \( b \) represent Kiran’s budget in dollars.

Which equation best represents Kiran’s budget?

A. \( 12s + 3p = b \)

B. \( 12 \cdot 10 + 3 = b \)

C. \( 1.50 + 2.99p = b \)

D. \( 1.50 \cdot 2.99 \cdot 2 = b \)
