The sentence that does the least to support the statement "Devon is our school's best athlete" is:
OB. Devon provides the best defensive tactics at basketball games.
This sentence talks about Devon's defensive tactics in basketball but doesn't directly mention any outstanding athletic achievements or performance that would support the claim of being the school's best athlete. The other options (OA, OC, and OD) provide specific instances of athletic success (scoring touchdowns, making winning goals, participating in track and field events) that showcase Devon's athletic abilities and support the statement better.
