Hey there,
Your question states: Today, the most common form of payment is. A. A cash card. . . .
Your correct answer would be (a debit card). You are going to see people use a (debit card) more than a (credit card). Not many people use a thing called a cash card. This may be known as a gift card and things of that sort. We no longer really use (cash) because in today's world, we view things as everything virtually. Many people as do not use (credit card) because some people know that they can not be as responsible. Your correct answer would be (a debit card)
Your clarified answer is :[tex]\boxed{ a \ debit \ card}[/tex]
Hope this helps.
