Hello Priyanshu,
As you asked for Best book for LU entrance so I would suggest you to go for Arihant publication books. You should go throughly to the mcqs and theory provide in the book as well .
On the other hand you can go for lucant books as well for more deep prepreation and conceptual knowledege.
Hope it helps.
Thank you :)
