Hii @Kawal
If you are willing to prepare for neet then the best book no doubt is your NCERT as most or I should say 97% of your exam questions are going to come directly from NCERT So first you should be thorough with your NCERTs and know each and every thing in that. After that we have many books in the market for objective practice as just knowing concept is enough you should practice things for that I have already written an answer you can check the link below 
All the best for your exam​:+1:
