Answer: A
Since the interaction between parties is electronic, there
is no inherent authentication occurring, therefore,
transaction authorization is the greatest risk. Choices B
and D are examples of risks, but the impact is not as great
as that of unauthorized transactions. Transmission delays
may terminate the process or hold the line until the normal
time for processing has elapsed, however there will be no
loss of data.
