Explanation:

Quantitative observations involve numbers and measurements. Statements B ("The bug was 5 cm long."), D ("The mass of the beaker was 122 g.") and E ("My fingernail is 2 cm long.") contain numerical measurements of length and mass. Statements A ("The candy was sour.") and C ("The flower is red.") are qualitative as they describe qualities (taste and color) without numbers.

B. The bug was 5 cm long., D. The mass of the beaker was 122 g., E. My fingernail is 2 cm long.
