Answer:  c. You have little risk of having your credit card number intercepted.
====================================
Explanation:
Choice A is false because it is an advantage to be able to choose goods from any vendor from anywhere in the world. The more competition, the better the outcome for the consumer.
Choice B can also be ruled out since that's also an advantage for the consumer. You don't have to worry about shop closure and that kind of time pressure is non-existent with online shops. 
Choice D is also a non-answer because shopping online is faster than shopping in a brick-and-mortar store. 
The only thing left is choice C. There is a risk a person's credit card could be intercepted or stolen. This usually would occur if the online shop isn't using a secure method of transmitting the credit card info, or their servers are insecure when they store the data. If strong encryption is applied, then this risk can be significantly reduced if not eliminated entirely.

The read-write type of memory helps in reading as well as writing data. This computer memory is used by users to continually update the data (to access (read from) or alter (write to) ) that is held on hardware storage devices. Internal or external hard disk drives, rewritable CDs or small flash drives can be all physical setups of read-write memory.
