B Correct answer
Explanation

Active mineral absorption requires energy (ATP) because minerals are moved against their concentration gradient from soil to root cells. This is an active transport process facilitated by carrier proteins in the cell membrane. Active water absorption is passive (osmosis), photophosphorylation produces ATP but doesn't directly drive mineral uptake, and vascular bundle cells facilitate transport but don't power it.
