Which of the following if statement conditions will check if x or y is equal to 8?

To test whether either variable equals 8 in Python you must write a comparison for each variable and combine them with the logical or operator (or). Each comparison produces a boolean; the or operator then yields True if either comparison is True.

Step-by-step analysis of each option:

a. if (x | y == 8):  
Due to operator precedence, y == 8 is evaluated first, so the expression is effectively x | (y == 8). That attempts a bitwise-or between x and a boolean — semantically wrong for testing equality of either variable, and will not correctly express “x equals 8 or y equals 8”.

b. if (x == 8) | (y == 8):  
This uses the bitwise-or operator | on the boolean results of the two comparisons. While Python allows (True | False) and it yields the same boolean result as True or False in many cases, | is not the logical operator and does not short-circuit; it’s the wrong operator choice for a normal boolean condition. The intended, idiomatic form uses the keyword or, so this option is not the correct standard answer.

c. if 8 == x or y:  
This parses as (8 == x) or y. If 8 == x is False, Python evaluates the truthiness of y (not whether y == 8). That means a nonzero/non-empty y will make the condition True even when y != 8. So this does not correctly test “y == 8”.

d. if x or y == 8:  
This parses as x or (y == 8) because == has higher precedence than or. The left operand x is evaluated for truthiness; if x is truthy the condition is True regardless of equality to 8. Thus it fails to correctly check x == 8.

e. if 8 == x or 8 == y:  
Each comparison is explicit (8 == x) and (8 == y) and they are combined with the logical or keyword. This correctly evaluates to True exactly when x equals 8 or y equals 8. (Using 8==x prevents accidental assignment in languages with = vs ==; in Python either x==8 or 8==x works the same.)

Therefore the correct choice is e. This matches the provided answer.
