In a MRP problem, $A$ is a MPS item. Every A requires $2$ B$\text{'}$s and $3C^{\text{'}}$ Every B requires $5$ C$\text{'}$s$.$ All lead times are two periods. All initial inventory values are $0.$ Use lot$-$for$-$lot method for order quantities for all items. What is the low level code $($LLC$)$ for B and C$?$

LLC for $B$ is $0$ and $C$ is $1$

LLC for both $B$ and $C$ are $2$

LLC for $B$ is $2$ and $C$ is $1.$

LLC for $B$ is $1$ and $C$ is $2$
