(C) For the given $A.P.$,the first term $a = -4$ and the common difference $d = -5$.The formula for the $n^{th}$ term of an $A.P.$ is given by $T_n = a + (n - 1)d$.To find the $12^{th}$ term,we substitute $n = 12$,$a = -4$,and $d = -5$ into the formula:$T_{12} = -4 + (12 - 1)(-5)$$T_{12} = -4 + (11)(-5)$$T_{12} = -4 - 55$$T_{12} = -59$.
