Answer:
a) Likert scale
Step-by-step explanation:
Likert scales are used to measure attitudes and opinions with a greater degree of nuance than a simple “yes/no” question.
"It’s a question that uses a 5 or 7-point scale, sometimes referred to as a satisfaction scale, that ranges from one extreme attitude to another. Typically, the Likert survey question includes a moderate or neutral option in its scale."
