Final answer:
The phrase "do I have to" is the correct form, asking about an obligation or requirement you might have. "Too" is incorrect in this phrase because it means "also" or "excessively". When in doubt, consider context and ensure correct usage and spelling.
Step-by-step explanation:
The correct phrase is "do I have to" rather than "do I have too". In this context, "to" is part of an infinitive verb form and does not mean "also" or "excessively", which is the meaning of "too". When you say "do I have to", you're typically asking if you are required to perform an action, perhaps due to rules, expectations, or necessity.
The questions you asked to consider when using the phrase "do I have to" are insightful. They can depend on the context of the situation, including physical laws, legal requirements, or other forms of obligation. While "take it" could imply accepting a situation or item as it is presented, the alternative "leave it" suggests declining or not involving oneself with the situation or item.
