Which government entity did jackson challenge as president a. congress b. the supreme court c. the vice presidency d. the national bank?

Hello.

The answer is 

D. The national bank.

He thought the bank was unfair for the amount  influence it had on the citizenz.
Jackson also objected to the bank’s unusual political and economic power and to the lack of congressional oversight over its business dealings. But, later he got censured for abussing his power for the world bank.
