Final answer:
None of the given options are always true. They are all conditional expressions that depend on the input value of the variable x. Option d) is an assignment, not a conditional check, and would always execute as 'true' but it's not a proper condition.
Step-by-step explanation:
The question you're asking is about evaluating different conditional expressions in a given code fragment to identify which of them will always be true. Let's take a look at each option:
- a) if( x < 3): This will only be true when the value of x is less than 3.
- b) if( x==1): This will only be true when the value of x is exactly 1.
- c) if( (x / 3) > 1 ): This will be true when the value of x is greater than 3, since integer division will yield a value greater than 1 only in that case.
- d) if( x = 1): This is not a comparison but an assignment. It will not check if x is equal to 1 but rather assign the value 1 to x, which is not a proper condition but will always be executed as true since the assignment will take place.
From the given options, none of the expressions are always true, as they all depend on the value that is input for x. However, looking closer at option d), if this were a conditional check (==) instead of an assignment (=), it would also only be true if x is equal to 1. Therefore, with the assumption that option d) is not correct due to its syntactical error as a conditional expression, none of these options is always true without further context on the value of x.
