What is the definition of the term that describes being exact and principled?

The term that describes being exact and principled is "scrupulous." This word carries the connotation of being diligent and precise, particularly when it comes to following moral and ethical principles. A scrupulous person is attentive to details and committed to a code of conduct, often ensuring that their actions align with their values. This term is frequently used in contexts where integrity and thoroughness are essential.

In contrast, the other options do not represent this meaning. "Smattering" refers to a superficial or scattered knowledge of something, which lacks the precision associated with being scrupulous. "Intercede" means to intervene on behalf of someone, which does not relate to the idea of being exact or principled. "Perpetrate" is to commit or carry out a harmful, illegal, or immoral act, which is the opposite of having a principled approach. This distinction reinforces why "scrupulous" is the term that accurately captures the essence of being exact and principled.
