Step 1: Understanding the Question:
The question asks for the correct definition of phishing.
Step 2: Key Formula or Approach:
Recall the standard cyber security meaning of phishing and match it to the option that describes fraud carried out through fake emails asking for confidential banking details.
Step 3: Detailed Explanation:
Phishing is a form of online fraud where attackers pretend to be a trusted organization, often a bank, and send emails that lead victims to fake websites or forms designed to steal PINs, passwords and other confidential details.
Option (A), a Govt. plan, is unrelated since phishing has nothing to do with any government scheme.
Option (B), a stem cell, is a biology term and has no connection to internet fraud at all.
Option (D), none of these, is wrong because option (C) already gives a correct and complete definition.
Step 4: Final Answer:
Phishing is a fraudulent way of getting PINs and bank passwords using emails, so option (C) is correct.
