Answer: (B)

In follow-up care after cancer treatment, there are two main approaches: active follow-up and passive follow-up. Active follow-up means a structured plan with regular clinic visits, imaging, and lab tests at defined intervals to detect recurrence early and manage late effects. Passive follow-up relies on patients to report symptoms and seek care as needed, with little routine surveillance. These two categories are the standard ways clinicians organize post-treatment surveillance, so the statement is true. In practice, programs may blend approaches or tailor them to cancer type and risk, but the core distinction remains between proactive surveillance and patient-initiated monitoring.
