Question: Which one of the following is an assignment statement in pseudocode?
Options:
 a. Total ← Total + 15
 b. Total * 3
 c. While total = 100
 d. If average < 200

Now, evaluating each choice:
Option a: Total ← Total + 15. This clearly shows an assignment operation where the value on the right-hand side (Total + 15) is computed and then stored into the variable on the left-hand side (Total). The arrow symbol is a common pseudocode convention for assignment, making this the correct type of statement.
Option b: Total * 3. This is an arithmetic expression that computes a product but does not assign the result to any variable. Without an arrow or an assignment operator, it merely represents a calculation, not an assignment.
Option c: While total = 100. This is a control structure with a condition, specifically testing whether total equals 100. It is not an assignment; instead, it represents a loop condition, so it does not perform variable assignment.
Option d: If average < 200. This is a conditional control structure that tests a condition (average less than 200). Like option c, it is not performing assignment, but rather directing program flow based on a condition.

In summary, only option a demonstrates assigning a computed value to a variable, which is the hallmark of an assignment statement in pseudocode, whereas the others either perform calculations without assignment or express control structures and conditions rather than assigning values.
