A 2010 Study Examining Whether Clean Scents Promote Reciprocity and Charity

A 2010 study examining whether clean scents promote reciprocity and charity found that:

A) participants in a clean smelling room gave more money to a partner, took more flyers related to volunteering efforts, and were more willing to donate more money than those in a room without a scent.
B) participants in a room with no noticeable scent gave more money to a partner, took more flyers related to volunteering efforts, and were more willing to donate more money than those in a room with a clean scent.
C) participants in a clean smelling room gave less money to a partner, took fewer flyers related to volunteering efforts, but were more willing to donate more money than those in a room without a scent.
D) participants in a clean smelling room gave more money to a partner, but took fewer flyers related to volunteering efforts, and were less willing to donate more money than those in a room without a scent.
