I was wondering if anyone could explain the answers for this question.

Reason one says that it is more extended which makes it more stable, is the reason for this because it allows more electron delocalization? Also, Reason 1 says that it is further stabilized by intramolecular h-bond. However, the reason notes that it is not a conjugated reason. Is this just something happens whenever there is an alcohol group close to nearby oxygen?

to the first part of your question: yes.  it's analogous to the playground example given in class regarding 1,3 pentadiene and 1,4 pentadiene

in regards to the second part of your question, it seems that intramolecular H-bonds are common among enol tautomers in general.
