Which of the following is NOT an Intra Uterine Device ?

Answer the question on the basis of passage given below :
Adsorption is a surface phenomenon which can be expressed by means of an empirical relationship know as Freundlich Adsorption isotherm. The relationship given by \(\frac{x}{m} = Kp^{\frac{1}{n}}\ (n > 1)\)
x = Mass of the gas adsorbed
m = Mass of adsorbent
p = Pressure at which adsorption takes place
K and n are constant
The curve of above relationship indicate that at a fixed pressure there is a decrease in physical adsorption with increase in temperature. At high pressure, curves become parallel to pressure axis, indicating saturation of the surface of adsorbent.
Adsorption of a gas follow Freundlich isotherm shown below. \(\frac{x}{m}\) is proportional to

List-I (Differential equation)	List-II (Integrating factor)
(A) \(x \frac{d y}{d x}-y=2 x^2\)	(I) \(e^{-y}\)
(B) \(\frac{d y}{d x}+\frac{y}{x}=2 x\)	(II) \(\frac{1}{x}\)
(C) \(x \frac{d y}{d x}+2 y=x^2 \log x\)	(III) \(x\)
(D) \(\frac{d x}{d y}-x=y\)	(IV) \(x^2\)

Choose the correct answer from the options given below:
