Colored aqueous solutions are a characteristic of transition compounds.

The only transition compound in the above choices is CrCl3.

Cr is a transition element.

OKG
Remaining all are not in series
only OKG is in series of(15,11,7)

Here it follows the random difference of '4'.

Envelope is a letter holder for one letter and in the question it mean that it holds one letter. Eye is also a word which starts and end with E but has one letter in the middle.

276+35961+50 = 10111011 = 1

The words in each pair are opposites of each other.

Here Mature and Regressed are opposite to each other. Then the required word should be opposite of varied and it is monotonous.

Hence, Mature : Regressed :: Varied : Monotonous.

Winter sleep of animals is called hibernation and summer sleep is called aestivation.

Hence, Winter : Hibernation :: Summer : Aestivation.

Given Circumference of a circular base of a cylinder = 44 cm

We know that Circumference of a circle = $$\begin{gathered} 2πr = 44 \\ ⇒r = 22π \end{gathered}$$

Now given the height of a cylinder h = 15 cm

Volume of a cylinder V = πr2h = π22π215 = 22 x 22 x 153.14 = 2311 cm3.
