Final answer:
If a person needs 75% or more help with dressing tasks like zipping or buttoning, they are considered to have full dependence.
Step-by-step explanation:
When a person requires 75% or more help with activities such as zipping, buttoning, or tying shoes during dressing, the level of assistance is typically considered dependent. This means that the person is unable to perform these tasks independently and requires substantial help. Therefore, the appropriate answer to the question, 'What assistance level is indicated when a person requires 75% or more help with zipping, buttoning, or tying shoes during dressing?' is d) Full dependence.
