A. they have a higher proportion of adenine-thymine than guanine-cytosine base pairs.

The option A represents the complete opposite of "high-gc gram-positive bacteria". High GC content means that this bacteria have more guanine ans more cytosine than the other base pairs - adenine-thymine. This means all the other options are correct.
