Am I the only one still stunned by (a)(2)?? TEN YEARS OLD?
It is a historical anachronism. Georgia used to have the death penalty available for rape. Those of you who are old enough remember the US Supreme Court's Furman case upsetting death penalty statutes nationwide. Following that, Georgia reenacted the death penaltt for all crimes of rape. In Coker v. Georgia, the U.S. Supreme Court said the death penalty was unconstitutional as a punishment for raping an adult woman.
So Georgia responded by making the rape of a female less than 10 years of age a death penalty offense. The Georgia Supreme Court upheld that statute as recently as 2008 (State v. Valazquez). The U.S. Supreme Court agains truck it down in Kennedy v. Louisiana as applied to the rape of a child.
So now this thing is sitting in the statute with no purpose, but it has nothing really to do with whether 10 year olds can consent.
Georgia's child molestation law has undergone some significant changes over the last few decades as well, many of them dealing with punishments and 10 year olds, but I do not remember all of the permutations.
Anyway, it is just a leftover from the old days with no real relevance today.
