Answer:
C is Snotase, because it works best in neutral environments (hence the pH of 7)
A is Flotase because it works best in acidic environments (low pH)
B is Zoomase because it works in acidic environments (low pH)
D is Floxase because it works in basic environments (pH above 7)
Note:
For pH, 7 is considered neutral. Anything below that is acidic and anything above that is basic.
Monsoon climate is generally great for rice farming, but monsoon floods can cause devastating landslides and floods.
