Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Oxidation Reduction
(1)
E.g.
Addition of oxygen
$2 M g + O_{2} \to 2 M g O$ (i)
e.g. Removal of oxygen
$C u O + C \to C u + C O$
(2)
e.g. Removal of Hydrogen
$H_{2} S + C l_{2} \to 2 H C l + S$ (ii)
e.g. Addition of hydrogen
$S + H_{2} \to H_{2} S$
(3)
e.g. Increase in oxidation number
$(+ 2) (+ 4)$
$S n C l_{2} \to S n C l_{4}$ (iii)
e.g. Decrease in oxidation number
$(+ 7) (+ 2)$
$M n O_{4}^{-} \to M n^{2 +}$
(4)
e.g. Removal of electron
$S n^{2 +} \to S n^{4 +} + 2 e^{-}$ (iv)
e.g. Addition of electron
$F e^{3 +} + e^{-} \to F e^{2 +}$
Oxidation is gain of oxygen. Reduction is loss of oxygen.

Assertion – The non-fusible impurities present in iron ore are removed by $C a C O_{3}$ .

Reason: $C a C O_{3}$ which decomposes into $C a O$ and $C O_{2}$ . The $C a O$ formed reacts with $S i O_{2}$ to remove silica

ASSERTION: n-Pentane and n-Hexane belong to a homologous series.

REASON: n-Pentane and n-Hexane belong to the same class of hydrocarbons and they differ by a - $C H_{2}$ - group.

Assertion: All the points (1, 0), (-1, 0), (2, 0) and (5, 0) lie on the x – axis.
Reason: Equation of the x-axis is y = 0
