A) A large proportion of the mail that is correctly addressed is damaged in transit.
B) No incorrectly addressed mail arrives within two business days of being sent.

Tough one.
I will go for D.

there are two situations in which the letter can take more than 2 days
X. It is damaged in its transit
Y. The address is incorrectly written on it.

First sentence tells that
Nearly all mail that is correctly addressed arrives at its destination within two business days

so there are very few mails that get damaged in transit.

But still
most mail arrives three business days or more after being sent

so the above Y must be true.

Option D clearly says this.

Thus D.

If the statements above are true, which one of the following must be true?
A) A large proportion of the mail that is correctly addressed is damaged in transit. explanation below
B) No incorrectly addressed mail arrives within two business days of being sent. - OOS no mention of incorrect addressing
C) Most mail that arrives within two business days of being sent is correctly addressed. possible, from statement 1 alone
D) A large proportion of mail is incorrectly addressed. - OOS no mention of incorrect addressing
E) More mail arrives within two business days of being sent than arrives between two and three business days after being sent. - speculating. there is no comparision b/w mails arriving within 2 days & mails arriving in 2-3days

For A -> mail addressed correctly reaches in 2 days. correctly addressed mail takes > 2 days when damaged in transit. Fact->most mail arrives 3 or more business days after sending.
So the most mails addressed correctly are damaged in transit.

Why eliminate C? -> I dont know between A & C i feel A is better & includes all the facts presented in the statement.

IMO A.
OA?
