Which of the following is considered a relevant factor in determining child custody?

Determining child custody involves assessing various factors that affect the well-being of the child. Sibling placement is a relevant factor because courts recognize the importance of maintaining familial bonds and the emotional stability that siblings provide to one another. Keeping siblings together can foster a sense of security, continuity, and familial support, all of which are vital for a child's development and well-being. Courts often consider how separating siblings might adversely affect their relationship and emotional state.

Other factors mentioned, such as race and the parent's sexual conduct, are generally not relevant to custody decisions under current law, as custody determinations are based primarily on the best interests of the child. While religion can influence family dynamics and values, its relevance may depend on the specific circumstances and how it impacts the child's upbringing. However, sibling placement stands out as a clear and recognized factor that directly supports the child's need for emotional ties and stability during custody arrangements.
