Correct answer choice is :
C) The people rebelled against high taxes.Explanation:

Then once Solomon died Rehoboam had the choice of either taking the taxes his father put on the kingdom away or keeping them, so he suggested his father's advisory who said take the taxes away and then he asked his friends who said make them higher.
