Choose the correct answer:Consider the following Activity:A)B)C)D)

The diagram displays an activity labeled "Account Authentication".

There are two main paths branching from the start of the activity:

One path leads to an activity named "Validate Password".

The other path leads to an activity named "Send OTP".

Both paths converge into a decision diamond labeled "Authentication Successful?".

Depending on the outcome of the decision (Yes/No), the flow continues to either a "Grant Access" or "Deny Access" activity.

Explanation of why Option B is Correct:

This diagram accurately represents the scenario of account authentication where there are two alternative paths for validation: using a password or an OTP (One-Time Password). The decision point after these paths merges the flow for a final decision on granting or denying access based on successful authentication.

Comparison with Other Options:

Option A, C, and D show different activity sequences that don't align with the two initial validation paths (password vs. OTP) and the subsequent decision point based on authentication success.
