Correct answer: A
Concept
In an email, the To and Cc recipient lists form visible header information. Every recipient who receives the message can normally read those visible recipient lists.
The Bcc recipient list is suppressed from the delivered header. Therefore, recipients do not learn the identities of Bcc recipients merely from the Bcc field, and one Bcc recipient does not thereby learn the identity of another Bcc recipient.
Application
X receives the message through Bcc and can read the visible Cc list containing U, so statement A is true.
U is a Cc recipient and can read the same visible Cc list containing V, so statement B is true.
W receives the message through Bcc, but the Bcc list containing X is hidden, so statement C is false.
V is a Cc recipient and can read the visible To field containing Y, so statement D is true.
Y is the To recipient and can read the visible Cc list containing V, so statement E is true.
Cross-check
The visibility rule separates A, B, D and E, which use visible To or Cc information, from C, which depends on hidden Bcc-to-Bcc information.
Contrast
A, B, D and E only matches the four claims based on visible To and Cc header entries.
C only depends on one Bcc recipient learning another Bcc address from the suppressed list.
C, D and E only includes the Bcc-to-Bcc claim but omits the visible Cc relationship used in A and B.
B and E only omits two additional claims that follow from the visible To and Cc lists.
Therefore, the true statements are A, B, D and E only.
