The correct decreasing order of oxidation state of the underlined atom in each molecule is

Two identical inductors are connected in two different configurations P and Q, where a time varying current $l(t)$ is flowing, as shown in the figure. The induced emf between points a and b for configuration P is $E_{P}$ and that for configuration Q is $E_{Q}$ The ratio $E_{P}/E_{Q}$ is: [Neglect the effect of mutual inductance.] [Image Placeholder]

A ray of light with wavelength $\lambda$ is incident on three different photoelectric cells namely 1, 2 and 3. The threshold wavelength of these photoelectric cells are $\lambda_{1}$, $\lambda_{2},$ and $\lambda_{3,}$ respectively and the magnitude of stopping potentials of these cells are $V_{1}$, $V_{2}$ and $V_{3},$ respectively. The relation between $\lambda$ and threshold wavelengths are $\lambda_{1}\lambda$ and $\lambda_{3}>>\lambda$. The correct option is:

Given below are two statements: Statement I: trans-But-2-ene upon treatment with $Br_{2}$ in $CCl_{4}$ gives the following product. [Image Placeholder] Statement II: cis-But-2-ene upon treatment with alkaline $KMnO_{4}$ gives the following product. [Image Placeholder] In the light of the above statements, choose the most appropriate answer from the options given below.

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R. Assertion A: In an experiment, Mendel observed that the F1 progeny plants are all tall and none are dwarf. Reason R: Stem height is a contrasting trait, with tall being dominant and dwarf being recessive. In the light of the above statements, choose the most appropriate answer from the options given below :
