Solution

The correct options are
B $\frac{1}{5 - 5}$
C $\frac{5}{- 0}$
Division by zero is not defined.

$(i) \frac{1}{5 - 5} = \frac{1}{0} \Rightarrow$ Not defined

$(i i) \frac{5}{- 0} = \frac{5}{0} \Rightarrow$ Not defined
$(∵ - 0 = + 0 = 0)$

$(i i i) \frac{1 - 1}{5} = \frac{0}{5} = 0$

$(i v) \frac{8}{5 - 1} = \frac{8}{4} = 2$
