Which of the following is true of sexual orientation? It is defined by a continuum of attraction. It involves choosing to be either heterosexual or homosexual. It consists of random, unpredictable sexual impulses. It is independent of emotional and romantic attraction.

A - It is defined by continuum of attraction.

Explanation:

An individual's sexual orientation is defined by a continuum of attraction to others. It is a pattern of romantic or sexual attraction or both to persons of any gender: the same, the opposite or both. Identification with any of the categories such as heterosexual, asexual, bisexual or homosexual has to do with our identities as well; with plenty other categories under them. How does an individual finds out who (as in what type of gender) is attracted to? Well, it's a continuum of attraction, a sort of pattern: if an individual has always been attracted to men (as a woman) it is most likely that she is heterosexual. But, if at some point she started to feel an attraction to women, that continuum that were behind men will, perhaps, "shift" unto women, making her bisexual.
