What is the primary function of a critical illness rider?

The primary function of a critical illness rider is to pay a lump sum if the insured is diagnosed with a critical illness. This rider is designed to provide financial support during a time when the policyholder may face significant medical expenses and loss of income due to illness. By offering a one-time payment upon the diagnosis of specified critical illnesses such as cancer, heart attack, or stroke, this rider helps individuals manage the financial burdens associated with treatment and recovery.

This coverage is particularly valuable as it allows policyholders to focus on their health and recovery without the added stress of financial concerns. It serves as a safety net, ensuring that they have access to funds that can be used for various needs, such as medical bills, rehabilitation, or even daily living expenses while they are unable to work.

Other options do not align with the intention of a critical illness rider. For example, additional coverage for accidental death is covered under a different type of rider. Increased payouts during retirement refer to retirement-focused products rather than critical illness. A premium discount for healthy lifestyle choices is more about incentivizing wellness rather than providing financial benefit during an illness. Thus, option B accurately encapsulates what a critical illness rider is designed to do.
