All angiosperms and some gymnosperm

The correct option is A.

Explanation of the correct option:

1. A vessel is a type of water-conducting tissue which is a part of the xylem.
2. Angiosperms are also called flowering plants and since all flowering plants have this water-conducting tissue, it's present in all angiosperms.

Option B:

Since angiosperms are known as flowering plants all angiosperms without any exception unlike gymnosperms have a water-conducting vessel.

2. Although gymnosperms of some kind do have vessels, pteridophyte lacks xylem vessels.

Option D:

Pteridophytes are seedless flowerless plants so they lack the xylem vessels which help in water transport.
