A customer purchases $3,000 of XYZ, which settles today in a margin account.

Under Federal Reserve Regulation T, customers must deposit at least 50% of the purchase price for margin trades. However, the minimum deposit requirement is $2,000, regardless of the 50% rule, if the account is below this threshold.

50% of $3,000 = $1,500.

Since $1,500 is less than the $2,000 minimum, the customer must deposit the full $2,000.

B is correct because $2,000 is the required minimum deposit.

A is incorrect because the $1,500 calculation does not meet the minimum.

C and D are incorrect because they exceed the minimum deposit requirement.
