Question

which tag is not closed tag ​

Answer 1

Answer:

The tags are optional because it's implied that a new tag would not be able to be started without closing it. These are the following: html, head, body, p, dt, dd, li, option, thead, th, tbody, tr, td, tfoot, colgroup . There are also tags that are forbidden to be closed: img, input, br, hr, meta, etc.
