Find the cost$-$effective way to reduce the completion time by $3$ days. For example, if your answer is to accelerate task $A$ by $1$ day, put down $A$ by $1$ in

the blank. When you need to accelerate multiple tasks at the same time, please identify them in a single step. For example, if your answer is to

accelerate $B$ and $C$ both by $1$ day, put down $BC$ by $1$ in the blank.
