As per an article on the Montreal Gazette dated $3$ November $2023,$ Hydro Quebec, Canada$$s biggest electricity producer, estimates it will need to expand annual generating capacity by between $8,000$ and $9,000$ MW in the next $12$ years to improve energy efficiency and significantly reduce power outages by increasing the capacity of existing generating stations and building new dams. Which of the following issue is the most important one meeting this ambitious plan according to this article:

a$.$

Seventy$-$five percent of the new generating capacity will be dedicated to decarbonizing the economy.

b$.$

The need to hire an average of $35,000$ construction workers a year until $2035$ to build future dams.

c$.$

Fossil fuels still represent about half of the energy consumed in the province despite Quebec$$s status as a leader in hydroelectric production.

d$.$

Detailed talks with First Nations communities will be required to proceed with the construction.
