Which attack is an example or social engineering?

An example of a social engineering attack is described in option A, where an email is used to impersonate a bank and deceive users into entering their bank login information on a counterfeit website. Social engineering attacks exploit human psychology rather than technical hacking techniques to gain access to systems, data, or personal information. These attacks often involve tricking people into breaking normal security procedures. The other options describe different types of technical attacks that do not primarily rely on manipulating individuals through deceptive personal interactions.
