Which of the following is used to open your account?

(A) Log out
(B) Sing out
(C) Log in
(D) None of these

🧠 Explanation:

Login is the action used to access your account on a computer, website, or application. It typically involves entering a username and password to verify identity and allow secure entry. This process protects personal information and ensures that only authorized users can reach the account’s data or features. Logging in is a basic step in digital security, used in email services, banking systems, and social media platforms. In grammar, “login” can be a noun (referring to the process or credentials) or a verb (to perform the action). Alternatives could be “sign-in” or “account access” in similar contexts.
