The learning curve coefficient LCC(10, 0.8) captures:

a. the cost to produce one unit in a process with c(1) = 1, a cumulative output of 10, and a learning rate of 0.8.

b. the cost to produce one unit in a process with c(1) = 10, a cumulative output of 1, and a learning rate of 0.8.

c. the cost to produce 10 units of output in a process with c(1) = 1, a cumulative output of 1, and a learning rate of 0.8.

d. the cost to produce 10 units of output in a process with c(1) = 1, a cumulative output of 10, and a learning rate of 0.8.
