D. frictional, structural, and cyclical unemploment.

Explanation:

Types of Unemployment

There are three basic types of unemployment which are the cyclical, frictional, and structural.

Cyclical Unemployment

Is due to the highs and lows of the economy, as in cycles e.g in times of recession, the job lost is know as cyclical unemployment.

Frictional Unemployment

It results from the actual turnover in the labor market and the time taken to get a new job. E.g. when a worker change his/her job, it requires time to get a name job and learn more of the job in details for him/her to be called up for interview and get hired. This process is termed frictionally unemployed.

Structural Unemployment

Originates from a lack for demand for a specific class of worker due to the worker lacking the appropriate skills needed by the employee as this can cause the worker to lose the job. Another example is sourcing for a reduced cost of labour abroad.

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
