Answer 1

I think it's the first one

Answer 2

Heading is the title at the start of a page or section. Chapters in books will often start off with their own heading/title.
The sub-heading is a secondary heading in this chapter or article. It contains stuff relevant to the Heading but is like a mini-topic related to the main title.
e.g: Heading: The Chemistry Elements
sub-heading: Iron
