[tex]\qquad\qquad\huge\underline{{\sf Answer}}[/tex]
Let's solve ~
[tex]\qquad \sf \dashrightarrow \: \dfrac{3 {x}^{2} y {}^{ - 1}}{27x {}^{ - 3} {y}^{8} } [/tex]
Now, let's get the common terms out :
[tex]\qquad \sf \dashrightarrow \: \dfrac{3 {x}^{2} y {}^{ - 1}}{3 {x}^{2} {y}^{ - 1}(9 {x}^{ - 5} {y}^{9} )} [/tex]
cancel out the common terms in numerator and denominator
[tex]\qquad \sf \dashrightarrow \: \dfrac{1}{9 x {}^{ - 5} {y}^{9} } [/tex]
[tex]\qquad \sf \dashrightarrow \: \dfrac{ {x}^{5} }{9 {}^{ } {y}^{9} } [/tex]
So, the correct choice is C
