7. A, upon request, lent his white van to his friend, B, to drive his wife C from Tarlac to XYZ Medical Center in BGC for treatment. On his way back to Tarlac and after leaving C at the hospital, people flagged the white van, thinking it was a UV Express for hire. B stopped and allowed the people to board and collected payment from them as if the van was a UV Express plying its route. As B was driving along the provincial road, a flash flood wrecked the white van. Is B liable to A for the loss of the white van? Reason(s).
