A pratice paper for web development. How does this have anything to do with HTML5? I could have sworn the answer was A.

Hola community!! Everyone going over this, please read this once and honestly answer my query.
I am on a probation at a startup. When i will be full-time, then the startup has promised me to provide CTC of 7,50,000(inr) i.e 10,000$ (usd).
Now I want to switch this startup company. Here are my reasons -
1. Less people, more work. - Well, that's what we call a startup. The tech team consists of 3-4 members only and we ourselves have to do the whole thing from end to end. This consists of designing the architecture, PR reviews, qa testing and coding ofcourse.
2. I see myself that I am capable enough to earn 1.5 times more than the above CTC. Also, all my friends are earning 2x the above ctc.
3. Also, there is no senior in the team except founder himself. This really seems awful as can't learn from anybody.
4. Also, i have plans of higher studying due to which i have to entrance exams. So i need to prepare them too. Switching to an established company can mean more money and less work.
Now, can anyone suggest me whether my reasons to switch are legit or vague??
