which of the following is a healthy blood pressure level? a. 120/95 b. 130/80 c. 110/75 d. 115/85

The healthy blood pressure level among the options given is closest to "a. 120," which likely refers to the systolic pressure of 120 mmHg, a value within the range considered normal or optimal blood pressure for most adults. Normal blood pressure is generally less than 120/80 mmHg, where 120 is the systolic and 80 is the diastolic pressure. The option "b. 13080" appears to be a typographical error as it is not a valid blood pressure reading format. The option "c. 110" might indicate a systolic pressure of 110, which is also within a healthy range but incomplete without a diastolic value. The option "d. 1" is not a valid blood pressure reading. Thus, from the options, "a. 120" is the best representation of a healthy blood pressure level, assuming it refers to the systolic pressure and is paired with an appropriate diastolic reading under 80 mmHg.
