Explanation:

To determine an untrustworthy source, we analyze each option:

• "It's from a person's personal blog": Personal blogs often lack fact - checking, editorial oversight, and are more likely to contain personal opinions or unsubstantiated claims, so this is a sign of an untrustworthy source.
• "It's been peer reviewed by other experts": Peer - reviewed sources are evaluated by experts in the field, which increases their trustworthiness.
• "It's been frequently cited in other sources": Frequent citation implies that the source is recognized and valued by other researchers, making it more trustworthy.
