If the cost per hour to operate Mine $2$ was $$220$: Would $(1,3)$ remain optimal? What minimum Cost could be realized?

Question $2$ options:

That represents an increase in the second objective function coefficient of $60,$ which is within the allowable increase of $40.$ Thus, $(1,3)$ will remain optimal. The minimum cost will be $$860$

That represents an increase in the first objective function coefficient of $60,$ which is within the allowable increase of $93.$ Thus, $(1,3)$ will remain optimal. The minimum cost will be $$860$

That represents an increase in the second objective function coefficient of $60,$ which is beyond the allowable increase of $40.$ Thus, $(1,3)$ will not remain optimal. However, we don't know $($without solving the "new" model$)$ what the minimum Cost would be
