Task: Instance Description Understanding (ontology: Sciences/Biology)

Which of the following definitions best describes the instance 'transeksüel'?

A. A mostly historical term used to refer to homosexual sexual activity in which at least one participant does not identify as gay, but who supposedly engages in such behavior due to an absence of heterosexual partners. For instance, in prisons, boarding schools, military bases, ships at sea, convents and monasteries, etc. This conceptualization often oversimplifies matters, ignoring situations which are nonconsensual, those in which comfortable experimentation may take place, and those in which admitting that one identifies as non-heterosexual might be dangerous. Therefore, it has fallen out of use.
B. Broadly, the state of being a eunuch, i.e. a male without testes; narrowly, a hypogonadism characterized by the lack of mature male germ cells and testicular hormones.
C. A term used selectively by some in the transgender community, historically used to refer to transgender persons who had undergone or desired to undergo gender confirming surgeries (particularly genitoplasty). This terminology can be somewhat pathologizing in its connection to "transsexualism" and its potential to be construed as a form of differentiating between "true" and "false" transgender persons. The term should generally be avoided, especially by cisgender persons, although it is notable that some trans people prefer the term, or reclaim it in select circumstances.
D. A person whose sexual habits are not considered acceptable.
