See explanation
Explanation:
If I am running my country, I will go for biomass as an energy resource. Biomass is cheap and readily available. The use of biomass in electricity generation is largely safe and reliable; it even ensures a clearer environment!
Biopower plants burn biomass directly to produce high-pressure steam which is now used to drive a turbine generator to generate electricity. Biomass will always be available at almost no cost hence it offers an inexpensive energy resource for electricity generation.

B. Indicator
Explanation:
An indicator is used to determine whether an acid or alkali has been added to a solution.
Indicators can be liquid or a paper called litmus paper. There also some digital forms of indicators that can tell whether an acid or alkali has been added to a solution.
- An acid and alkali will change the pH of a solution.
- pH is the amount of hydrogen ions that are in a solution
- So, these changes in the pH when an acid or alkali is introduced is usually monitored using indicators.
- Examples of indicators are litmus paper, methyl orange, methyl red, bromothymoblue
