Answer 3

if you think logically it is obvious to not have be tag in pair.
because mainly tag pairs are used to apply different types of text formatting on the text enclosed by the tags,
but in case of line breaks you need the break, only this much info is sufficient.
correct me if you am wrong.

Answer 4

no </br>
