Which insulin is long-acting?

Explanation:
Long-acting insulins provide basal coverage by releasing insulin slowly over an extended period. Ultralente is formulated to release insulin gradually, producing a prolonged effect that can last up to about 24 hours, which fits the long-acting category. The other options have shorter onset and duration profiles: Regular insulin is short-acting, Lispro is rapid-acting, and NPH is intermediate-acting. That combination of slow, extended action makes Ultralente the best choice for long-acting insulin.
