Admissions are not: 

Admissions are statements that suggest an inference as to any fact in issue or relevant fact, made by a party to a proceeding or by someone legally authorized. While admissions are relevant and admissible, they are not binding as conclusive proof. They may be rebutted or explained and are treated as evidentiary material rather than final proof. Their weight depends on the circumstances and credibility. The law allows the opposite party to counter or clarify the admission. Therefore, Option C is correct as it clarifies that admissions are not absolute or conclusive in nature, unlike presumptions under specific sections.
