A) constant returns to scale, because the line through the origin is linear.
B) decreasing returns to scale, because the isoquants are convex.
C) decreasing returns to scale, because doubling inputs results in less than double the amount of output.
D) increasing returns to scale, because the isoquants are convex.
E) increasing returns to scale, because doubling inputs results in more than double the amount of output.
