Lampblack is used in making
A.Shoe polish
B.Black paint
C.Ink
D.All of these

Answer 1

Hint: In the given question we have to find out what is Lampblack and then we can use that information to find what resources are used. Now it is a petroleum product obtained by incomplete combustion and is black in colour. It is also widely used in the industry in plastics, paints, and inks and many others.

Complete Step by step Solution:
The given question is asked about the things that are partially or most prominently made by the use of the lampblack. Now these products must have lampblack as one of their constituents, may be in derivative or the state form. Firstly we need to know what exactly is the lampblack.
Lampblack is a subtype of Carbon black which is a material that is produced by the process of incomplete combustion. The combustion is done of various heavy petroleum products namely the FCC tar or coal tar. If we talk about the uses then we can say that lamp black is predominantly used in the reinforcing filler in tires and other rubber products. Apart from that it is also widely used in plastics, paints, and inks, as a color pigment for the purpose of colouration .
This means that all of the products enlisted are made using it.

Therefore, the correct option would be option D.

Note: Carbon black is a form of paracrystalline carbon that has a high surface-area-to-volume ratio, albeit lower than that of activated carbon. It is dissimilar to soot in its much higher surface-area-to-volume ratio and significantly lower (negligible and non-bioavailable) polycyclic aromatic hydrocarbon (PAH) content
