Consider a price-taking firm that uses labour (L) and capital (K) to produce output according to thefirm's production functionf(K,L)=26L^1/3.K^2/3.If the firm is minimisingits production costs and if the price of labouris 3 times the price of capital, then its chosen input bundle should satisfy:

K=6L

K=12L

K=L/12

K=L

K=2L
