Which ethical guideline would a scientist be breaking if the scientist videotaped children, without asking their guardians, while the children were taking a test in class?

Privacy

Explanation:

In research, privacy is a concept that ensures that if human participants are used, they have a right to privacy when they are participating in a research. For children who may not be of age to understand the concept of privacy, their parents or guardian would be informed about the research and consent will be given. However the scientist that failed to ask the parent or guardian and videotaped children while taking a test has interfered in the privacy of these kids.

there are no options provided but you can choose among the following gender-neutral pronouns: zir, hir, eir, vis, tem, eir.

in the normal course of maintaining a pronoun-antecedent agreement, we could have used the words his or her but since we are also required to use gender-neutral language, we need to replace it with its equivalent gender-neutral pronoun.

giant impact theory - the moon was formed from the collision between earth and another mars-sized body.

colliding planetesimals hypothesis - the moon was formed from the same cloud of material as earth.

capture hypothesis - the moon was locked into orbit by earths gravity as it was passing by it.

accretion hypothesis - the moon was formed from collisions and combining of planetesimals.

i think this is right, if not and you know better let me know.
