Final answer:
The most favorable definition of total disability in a disability insurance policy is 'Own Occupation,' as it allows policyholders to receive benefits if they cannot perform their own job, even if they can work elsewhere.
Step-by-step explanation:
The most favorable definition of total disability in a disability insurance policy is B. Own Occupation. This definition allows policyholders to be considered totally disabled if they are unable to perform the duties of their specific occupation, even if they can work in a different capacity. This is contrasted with other definitions like Any Occupation, which requires individuals to be unable to perform the duties of any job for which they are qualified by education, training, or experience. The Modified Own Occupation is similar to Own Occupation but typically with certain restrictions and may consider the individual's ability to work in related fields. Finally, Split Definition combines aspects of Own Occupation and Any Occupation over different periods within the policy's term.
