A prosecution for theft of property exceeding $100,000 in financial exploitation of an elderly person or a person with a disability may be commenced within _____ years of the last act committed.

The correct answer reflects that the prosecution for theft of property exceeding $100,000, particularly concerning the financial exploitation of an elderly person or a person with a disability, can be initiated within seven years of the last act committed. This timeframe is significant because it allows for sufficient time to gather evidence and build a case against the alleged offender. The law recognizes the particular vulnerabilities of elderly individuals and those with disabilities, ensuring that they have the legal protections necessary against exploitation.

In terms of the other options, they may suggest either too short a timeframe or an excessively long one that does not align with statutory limits for such serious offenses. Understanding these timelines is crucial for law enforcement and legal practitioners as they navigate cases involving theft and exploitation in these sensitive demographics.
