Product A is assembled from $3$ components: E $(4$ units needed to make one unit of A$),$ H $(10$ units$),$ and B $(1$ unit$).$ B is made of D $(10$ units$)$ and C $(5$ units$).$ D is made of H $(20$ units$).$ C is made of H $(10$ units$).$ Currently $25$ units of B and $6000$ units of H are in stock. Product A takes $3$ days to assemble, subassembly takes $4$ days, and order lead time is $4$ days for H and $6$ days for E$.$ Which of the following is true if $450$ units of A are needed by day $20?$
