[amp_mcq option1=”(age) > 65″ option2=”(age > 0 and < 10)" option3="(sales > 500 && < 800)" option4="(sales > 100 && sales <= 1000) E. (sales > 100 || sales <= 1000)" correct="option2"]
The correct answer is E. (sales > 100 || sales <= 1000).
A valid condition for an if statement must be syntactically and logically valid. Syntactically valid means that the condition follows the rules of the programming language. Logically valid means that the condition is true or false, and that it makes sense in the context of the program.
Option A is not syntactically valid because it does not have a closing parenthesis. Option B is not logically valid because it is impossible for a person’s age to be both greater than 0 and less than 10. Option C is not logically valid because it is impossible for sales to be both greater than 500 and less than 800. Option D is not logically valid because it is impossible for sales to be both greater than 100 and less than or equal to 1000. Option E is both syntactically and logically valid because it is possible for sales to be greater than 100 or less than or equal to 1000.
In conclusion, the correct answer is E. (sales > 100 || sales <= 1000).
