Which of the following is an accepted payment method by Sola?

The payment method accepted by Sola that includes a credit card with a 2% fee is considered valid because it allows for a flexible and convenient option for clients who prefer using credit cards for their transactions. Credit cards are widely used and provide benefits such as reward points and consumer protection, making them an appealing choice for many. The inclusion of a nominal fee is common in such transactions, as it helps businesses cover processing costs associated with credit card payments.

Other methods, while potentially acceptable in different contexts, may not align with Sola's policies. Cash payment, for example, may limit transaction tracking and safety. Checks also carry risks, such as potential non-sufficient funds and longer processing times. A bank transfer with a 1% fee could be acceptable in some scenarios but may not be as convenient for customers as using a credit card, which offers immediate transaction confirmation and easier record-keeping for both the business and the consumer.
