Again, In this question too you need to substitute the given variable values into the original expressions. Here, "x" is given as a value of "12" and the variable of "y" is given as as value of "2". A single variable of "x" in the numerator is given in the expression. On the denominator the variable of "y" with a value of "2" is multiplied by a numbered value of "3". So, now showing this by the help of LaTeX.
[tex]\mathbf{Since, \: x = 12, \: y = 2}[/tex]
[tex]\mathbf{\therefore \quad \dfrac{12}{3 \times 2}}[/tex]
[tex]\mathbf{\therefore \quad \dfrac{12}{6}}[/tex]
[tex]\mathbf{2}[/tex]
[tex]\boxed{\mathbf{\underline{\therefore \quad Final \: \: Answer \: \: is: \: B) \: 2}}}[/tex]
Hope it helps.
