Actually shortage may exist in this case, but option B is still incorrect.
Here's why,
the statement says, ' there is a shortage of gifts for all customers '
while ALL is the keyword.
For customers who queue at the first place, they face no shortage and can definitely acquire the coupons as they are at a prior to do so.
Therefore, although there may be a shortage of gifts, it is not for ALL customers.
Therefore, statement B is incorrect.
