\underline{\textbf{Given:}}

\mathsf{\left(\dfrac{x-2}{2}\right)\div\left(\dfrac{x^2-4}{3}\right)}

\underline{\textbf{To simplify:}}

\mathsf{\left(\dfrac{x-2}{2}\right)\div\left(\dfrac{x^2-4}{3}\right)}

\underline{\textbf{Solution:}}

\mathsf{Consider,}

\mathsf{\left(\dfrac{x-2}{2}\right)\div\left(\dfrac{x^2-4}{3}\right)}

\mathsf{=\dfrac{x-2}{2}\times\dfrac{3}{x^2-4}}

\mathsf{=\dfrac{x-2}{2}\times\dfrac{3}{x^2-2^2}}

\mathsf{Using\;the\;identity,}

\boxed{\mathsf{a^2-b^2=(a-b)(a+b)}}

\mathsf{=\dfrac{x-2}{2}\times\dfrac{3}{(x-2)(x+2)}}

\mathsf{=\dfrac{1}{2}\times\dfrac{3}{(x+2)}}

\mathsf{=\dfrac{3}{2(x+2)}}

\mathsf{=\dfrac{3}{2x+4}}

\underline{\textbf{Answer:}}

\mathsf{Option\;(A)\;is\;correct}
