its obviously female. "What my gender is not" makes it negitive, "but actually is" makes it positive "so it's not a lie" has no purpose, and "although that has been just said is a false truth" makes it negitive
I should point out that this is worded quite interestingly. Essentially, both options are wrong AND correct at the same time, due to the fact that "false truth" can refer to "What.. ..lie" or it can refer to the entire statement. The answer? Don't vote, but instead explain it.
