Answer:
Interval scale.
Explanation:
'Interval scale' is demonstrated as the mensuration scale that measures the quantitatively meaningful difference among the two variables. Such a scale measures the variable in their authentic form instead of measuring them relatively.
As per the given description, the response options presented would be considered as being measured on an 'interval scale' as the evaluations are quite clear and meaningful. The observation is done on the basis of the original form and thus, the differences are quite precise and absolute('strongly agree or strongly disagree'). There is no middle way round.
