Will give brainliest plz help

Answer:
Enzyme A - Flotase
Enzyme B - Zoomase
Enzyme C - Snotase
Enzyme D - Floxtase
Explanation:
This question is testing your knowledge of the pH scale. The information provided gives you information about what pH environments the enzymes work best in. We also have the information from the experiment showing the optimum pH.
Snotase works in neutral environments. A neutral environment is a pH of 7, which corresponds to enzyme C.
Flotase works in EXTREMELY acidic environments. The most acidic environment we have is for an optimal pH of 1, which corresponds to enzyme A.
Zoomase works in acidic environments, which corresponds to a pH of 3, the optimum for enzyme B.
Floxase works in basic environments, which are pH of more than 7, which is enzyme D.
