Given below are two statements :

Statement I : Gallium is used in the manufacturing of thermometers.

Statement II : A thermometer containing gallium is useful for measuring the freezing point (256 K) of brine solution.

In the light of the above statement, choose the correct answer from the options given below :

Match column I with column II

Assertion (A): Ga is used in thermometer
Reason (R): Melting point of Ga is low where as boiling point is high

Given below are two statements : one is labelled as Assertion $\left(\mathrm{A}\right)$ and the other is labelled as Reason $\left(\mathrm{R}\right)$.
Assertion (A) : Melting point of Boron $(2453 \mathrm{K})$ is unusually high in group $13$ elements.
Reason (R) : Solid Boron has very strong crystalline lattice.
In the light of the above statements, choose the most appropriate answer from the options given below ;

Assertion: Boron has high melting point (2437K)

Reason : Solid boron has strong crystalline lattice.

Boron has an exceptionally high melting point in the group $13^{\mathrm{t}\mathrm{h}}$ elements, because–
