Final answer:
An observation option (A) is the use of senses to record information, like seeing a gauge's pressure reading rise when air is filled into a tire.
Step-by-step explanation:
When you use your senses (sight, hearing, touch, taste, smell) to record what is happening or has happened, it is referred to as an observation option (A). Observations are the active acquisition of information from a primary source, and can be either qualitative, describing properties without numbers, or quantitative, involving measurements and numbers. An example of an observation is noticing that the pressure reading on a gauge increases when air is filled into a car tire.
