Which among the following react with Hinsberg's reagent?

Choose the correct answer from the options given below:

Given below are two statements :
Statement (I): Experimentally determined oxygen-oxygen bond lengths in the \(\mathrm{O}_3\) are found to be same and the bond length is greater than that of a \(\mathrm{O}=\mathrm{O}\) (double bond) but less than that of a single \((O-O)\) bond.
Statement (II) : The strong lone pair-lone pair repulsion between oxygen atoms is solely responsible for the fact that the bond length in ozone is smaller than that of a double bond \((\mathrm{O}=\mathrm{O})\) but more than that of a single bond \((\mathrm{O}-\mathrm{O})\).
In the light of the above statements, choose the correct answer from the options given below :

The Total pressure observed by mixing two liquid \(A\) and \(B\) is \(350\,mm\,Hg\) when their mole fractions are \(0.7\) and \(0.3\) respectively.The Total pressure becomes \(410 \,mm\,Hg\) if the mole fractions are changed to \(0.2\) and \(0.8\) respectively for \(A\) and \(B\). The vapour pressure of pure \(A\) is \(...........\,mm\,Hg\). (Nearest integer) Consider the liquids and solutions behave ideally.

In the potentiometer, when the cell in the secondary circuit is shunted with 4 \(\Omega\) resistance, the balance is obtained at the length 120 cm of wire. Now when the same cell is shunted with 12 \(\Omega\) resistance, the balance is shifted to a length of 180 cm. The internal resistance of cell is ___________ \(\Omega\).

Let a plane \(P\) pass through the point \((3,7,-7)\) and contain the line, \(\frac{x-2}{-3}=\frac{y-3}{2}=\frac{z+2}{1} .\) If distance of the plane \(P\) from the origin is \(d\), then \(d^{2}\) is equal to \(.....\)

In an experiment to determine the Young's modulus, steel wires of five different lengths \((1,2,3,4\) and \(5\,m )\) but of same cross section \(\left(2\,mm ^{2}\right)\) were taken and curves between extension and load were obtained. The slope (extension/load) of the curves were plotted with the wire length and the following graph is obtained. If the Young's modulus of given steel wires is \(x \times 10^{11}\,Nm ^{-2}\), then the value of \(x\) is
