Why write backticks in sql queries?

Question

SQL

Hello!
I meet 2 types of sql queries:
1) SELECT `id` FROM `table` WHERE `column` = 'value'
2) SELECT id FROM table WHERE column = 'value'
From here I have a question, why do I need to write apostrophes in a sql query and which option 1 or 2 is more correct and why?

Answer 1

why do you need to write apostrophes in sql query

This is escaping in case of using reserved words in table and column names.

which option 1 or 2 is more correct and why

It is correct to write with escaping, because the names can come from anywhere and anything can be there.
