Answer 1

According to me 1 and 3 should be wrong
Second is perfectly fine... If you think that the answer was wrong, you can report the question... The option is at the top right corner...

Answer 2

First and third sentence are wrong because the <a> tag doesn't accept the src attribute
The second sentence is wrong because the value of the attribute href may be start with "https" instead of http
