Analyzing the given pseudocode for potential anomalies in data flow:

Declare C, F, Z Decimal Set Z = 32 Read F Set C = (F-Z) * 5/9 Free C, F, Z Print F

The potential anomaly is with variable F. It is used after being freed, which typically indicates an error in managing the variable's lifecycle within the code.

Explanation: Freeing a variable typically indicates that it is no longer available for use, but F is used after this operation, which could result in undefined behavior or errors.

To determine the minimum quantity of test cases that will give 100% statement coverage, we need to ensure that each executable statement in the code is executed at least once. Let's analyze the code step by step to identify the necessary paths:

Valid account number and active account:

Crediting money to the account.

Old balance < zero, new balance >= zero (overdraft cleared).

VIP customer: message sent by email.

Valid account number and active account:

Crediting money to the account.

Old balance < zero, new balance < zero (account overdrawn).

Non-VIP customer.

Valid account number and active account:

Crediting money to the account.

Old balance >= zero.

VIP customer: message sent by email.

Valid account number but inactive account:

Set message "A/c inactive".

Send message by email to supervisor.

Invalid account number:

Add to the count of invalid inputs.

Considering these scenarios, we can see that the minimum number of test cases to cover all statements is three:

Path with a valid, active account, old balance < zero, new balance >= zero, and VIP customer.

Path with a valid, active account, old balance >= zero, and non-VIP customer.

Path with an inactive account or invalid account number.

Therefore, the correct answer is D. 3.

In the provided pseudo-code for the Bingo program, the variable MIN is used in the statement MIN = MIN + A without being initialized with a value beforehand. This represents a classic 'use before define' anomaly, as the variable MIN must have an initial value before any operation like addition can be performed on it.
