\(\frac{y}{z} = 1.5\) and \(z = 2\)
=> \(y = 1.5 * z = 1.5 * 2 = 3\)
Also, \(\frac{x}{y} = 1.5\)
=> \(x = 1.5 * y = 1.5 * 3 = 4.5\)
So, correct answer is option C.

\(\frac{x}{y} = \frac{y}{ z} = \frac{3 }{ 2}\) and z = 2
=> \(\frac{y}{ 3} = \frac{3 }{ 2}\) and therefore y = 3
=> \(\frac{x}{3} = \frac{3 }{ 2}\) and therefore \(x = \frac{9}{2} = 4.5\)
Answer C
