Dear aspirant,

The questions asked in jee are very different in compared to any state level entrances or any other private college entrances. Because in jee you have to be very observant , a good thinker, accurate all at the same time.

The options given in the jee exams are so similar that even a single mistake can give you the incorrect option. So you have to be very clear about what you are choosing. So I would suggest choose the option only if you are 90% sure that this is the correct answer.
