Step 1: Understanding Hypertension.
Hypertension, or high blood pressure, is typically diagnosed when either the systolic or diastolic pressure exceeds certain thresholds. Systolic pressure refers to the pressure when the heart beats, and diastolic pressure refers to the pressure when the heart is at rest.
Step 2: Analyzing the options.
- (A) Systolic BP 120 & Diastolic BP 60 mmHg: This is not considered hypertension, as normal blood pressure is typically around 120/80 mmHg.
- (B) Systolic BP 110 & Diastolic BP 70 mmHg: This is within a normal or slightly elevated range, but it is not hypertension.
- (C) Systolic BP 90 & Diastolic BP 140 mmHg: This is incorrect, as diastolic pressure of 140 mmHg is extremely high and suggests a medical emergency, but the systolic pressure is lower than the accepted threshold.
- (D) Systolic BP 140 & Diastolic BP 90 mmHg: This is the correct answer. A blood pressure reading above 140/90 mmHg is typically classified as hypertension.

Step 3: Conclusion.
Therefore, the correct answer is (D) Systolic BP 140 & Diastolic BP 90 mmHg, as this is the threshold for diagnosing hypertension.
Final Answer: (D) Systolic BP 140 & Diastolic BP 90 mmHg.
