The correct answer to the question is option B. 48
The Mean of a set of data can be obtained by taking the Summation of the data divided by the number of data i.e

With the above formula, we can obtain the mean of the data given in the question above as follow:
Summation of data = 60 + 45 + 20 + 70 + 45
= 240
Number of data = 5
<h3>Mean =? </h3>

<h3>Mean = 48</h3>
Therefore, the mean of the data is 48.
Thus, option B. 48 gives the correct answer to the question.

The correct answer is C. viscosity.
You can check the viscosity of the brake-fluid with using a voltmeter. You can see that by using the voltmeter and read on it the volts, the bigger the voltage the bigger the moisture in brake-fluid, thus less viscosity.

Answer:
The correction option is General Adaptation Syndrome (GAS) which was promulgated by Hans Selye, MD, Ph.D.
Explanation:
According to Hans, there are 4 stages of stress namely:
1. Alarm Reaction
Upon being stimulated by stressors, the body responds with a "fight-or-flight" response and actuates the sympathetic nervous system as the body's resources are mobilized to meet the threat or danger.
2. Resistance
The body fights and compensates while the rest and the digestive system attempt to restore certain body systems to healthy levels as the body focuses energy toward the stressor and stays on defense.
3. Exhaustion
If the stressor or stressors persist beyond the capability of the body, the resources become fatigued and the body becomes prone to morbidity and mortality.
