Final answer:
The correct punctuated sentence is option a. The newlyweds are trying to save money, so they clip coupons and buy items on sale.
Step-by-step explanation:
The correct punctuated sentence is: a. The newlyweds are trying to save money, so they clip coupons and buy items on sale. This sentence uses the conjunction 'so' to show cause and effect, indicating that the action of clipping coupons and buying items on sale is a result of the newlyweds' goal to save money.
In option b, the use of 'although' introduces a contrast or contradiction, which does not match the context of the sentence. Option c utilizes 'but', which may suggest a contradiction or opposition, but it does not align with the intention of the newlyweds to save money.
