Step 2: Analyzing the options.
(A) Qualitative: Incorrect. Time is a numerical quantity, not a qualitative variable.
(B) Discrete: Incorrect. Discrete variables take distinct, countable values. Time is continuous and can take any value within a range.
(C) Continuous: Correct. Time is a continuous variable as it can take any value within a specific range.
(D) Normal: Incorrect. Normal refers to a distribution, not a type of variable.
Step 3: Conclusion.
The correct answer is (C) Continuous, as time is a continuous variable.
Final Answer:} Continuous.
