B) Destroying abnormal tissue

Explanation: RF Ablation is a medical procedure primarily used to destroy abnormal tissue, such as tumors or arrhythmic heart tissue, through the application of radiofrequency energy.

B) It employs high-frequency electrical currents to generate heat

Explanation: RF Ablation works by using high-frequency electrical currents to generate heat, which then destroys the targeted abnormal tissue.

C) Various types of tumors and arrhythmias

Explanation: RF Ablation can be used to treat a variety of conditions, including tumors and arrhythmias, making it a versatile treatment option in modern medicine.

B) It is less invasive

Explanation: One of the main benefits of RF Ablation is that it is less invasive than traditional surgery, often resulting in shorter recovery times and reduced risks associated with surgical procedures.

C) Localized pain or discomfort

Explanation: A common side effect of RF Ablation is localized pain or discomfort at the site of the procedure, which is generally temporary and manageable.
