They mean A.
They simply mean it usefully as opposed to pedantically.
If you take it pedantically, it's not true... as there are electricians in biology departments who change light bulbs without needing the light of evolution.
Like the statement ALL cars have 4 wheels.
It's meant to be taken usefully instead of pedantically.
Most cars do have 4 wheels... to the point of almost all.
However, there are cars with busted tires, cars on blocks, 3-wheeled cars... and a few other insignificant alternatives.
None of these change the statement of ALL cars have 4 wheels being usefully correct in any normal, acceptable way of speaking.
Just as any minor, insignificant fractional alternative doesn't change the statement of NOTHING in biology makes sense except in the light of evolution.
You seem to want to declare a pedantic victory.
If that's what you're aiming for, crow away... it will be a silent celebration.
Meanwhile, everyone else will move along without a reason to change their minds that it's still perfectly valid and true to state that NOTHING in biology makes sense except in the light of evolution.
