Final Answer:
The crime of unlawful sexual intercourse (PC 261.5) may be committed by (a) Any adult with a minor.
Step-by-step explanation:
The crime of unlawful sexual intercourse, as defined by Penal Code 261.5, involves engaging in sexual activity with a minor. Option (a) "Any adult with a minor" aligns with this legal provision. The law deems individuals under a certain age (the minor) incapable of providing legal consent for sexual activities. Therefore, engaging in sexual intercourse with a minor constitutes a criminal offense.
Consenting individuals of the same age would typically not fall under the purview of this specific law, as it primarily addresses the issue of age-related consent. Marriage or parental consent does not exempt an adult from committing the crime if the other party involved is a minor.
Understanding the legal framework surrounding age of consent is vital for preventing and addressing instances of unlawful sexual intercourse and protecting minors from exploitation.
Option A is correct.
