Step-by-step explanation:

consider 4 book of political science,ps as 1 bundle,

3 books of environmental science, es as 1 bundle,

2 books of artificial intelligence,ai as 1 bundle

3 bundles can arranged in 3! ways = 6 ways

case 1 : each bundle has different books

if ps books are 4 different books on ps,

similarly if es bundle has 3 different books on es

and ai bundle have 2 different books on ai

then 6×4!×3!×2! ways they can be arranged = 1728

case 2: each bundle has same books

if the ps bundle has 4 same books, es has 3 same books, ai has 2 same books then no. of ways = 6
