Which of the following is not a mineral of fluorine?

Given below are two statements: one is labelled as Assertion $(A)$ and the other is labelled as Reason $(R).$
Assertion $(A):$ $ICl$ is more reactive than $I_{2}.$
Reason $(R):$ $I-Cl$ bond is weaker than $I-I$ bond.
In the light of the above statements,choose the most appropriate answer from the options given below:

Hydrolysis of $NCl_3$ gives $NH_3$ and $X$. Which of the following is $X$?

Given below are two statements: Statement $(I)$: Oxidising power of halogens decreases in the order $F_2 > Cl_2 > Br_2 > I_2$, which is the basis of "Layer test". Statement $(II)$: "Layer test" to identify $Br_2$ and $I_2$ in aqueous solution involves the oxidation of bromide or iodide into $Br_2$ or $I_2$ respectively with $Cl_2$, which is a type of displacement redox reaction. In the light of the above statements, choose the correct answer from the options given below:

Which of the following are correct matches?
$(a)$ $ClO_4^- > ClO_3^- > ClO_2^- > ClO^-$ (Stability order)
$(b)$ $Cl_2 > Br_2 > F_2 > I_2$ (Bond energy)
$(c)$ $OF_2 < OH_2 < OCl_2$ (Bond angle)
$(d)$ $I^- > Br^- > Cl^-$ (Reducing power)

$HBr$ and $HI$ can reduce sulfuric acid; $HCl$ can reduce $KMnO_4$. Which of the following can $HF$ reduce?
