Answer: A) Phishing
Explanation:
Phishing is type of attack in computer field that is processed to hack or steal the data of authorized user.The attacker acts as trusted party and then interacts with the authorized user through email or messages to gain confidential information like pin code, credit card number, login details etc of that user.
