Melting point of silicon is
Higher than B
Lower than Al
Higher Than C
Lower than C
As we have learnt,
The melting point data is given below :
Element Melting point in K
B 2553
Al 933
C 4373
Si 1693
From the above data, it is evident that the Melting point of Silicon is lesser than that of Carbon.
Therefore, option (4) is correct.
