Below are two statements, one labeled as Assertion $(A)$ and the other as Reason $(R):$
Assertion $(A)$: Among group $13$ elements, boron's melting point is unusually high $(2453 \mathrm{~K})$.
Reason $(R):$ Solid boron has a strong crystalline lattice.
In the context of the above statements, choose the correct answer from the following options:
A
Both $A$ and $R$ are true, but $R$ is not the correct explanation of $A.$
B
Both $A$ and $R$ are true, but $R$ is the correct explanation of $A.$
C
$A $ is true, but $R$ is false
D
$A$ is false, but $R$ is true
(JEE MAIN-2024)
Solution
Solid Boron has very strong crystalline lattice so its melting point unusually high in group $13$ elements
