Explanation
Choice A reason: This is incorrect because insulin glargine has a longer duration than 6 to 10 hr. Insulin glargine is a long-acting insulin that provides a steady and continuous level of insulin in the blood. It is usually given once daily at the same time.
Choice B reason: This is incorrect because insulin glargine has a longer duration than 3 to 6 hr. Insulin glargine is not a short-acting or rapid-acting insulin that peaks quickly and lasts for a few hours. It is a long-acting insulin that does not have a peak and lasts for up to 24 hr.
Choice C reason: This is incorrect because insulin glargine has a longer duration than 16 to 24 hr. Insulin glargine is a long-acting insulin that can last for up to 24 hr, but not more than that. It is not an ultra-long-acting insulin that can last for more than 24 hr.
