Answer : The correct option is, (B) Germanium

Explanation :

As we know that the material are divided into three categories which are conductors, insulators and semiconductors.

Conductors : It is a type of substance which conduct electricity that means it allow the electrons to flow through them.

Example of conductors are, iron, aluminium, gold, etc.

Insulators : It is a type of substance which does not conduct electricity that means it does not allow the electrons to flow through them.

Examples of insulators are, glass, rubber, ceramics, etc.

Semiconductors : It is a type of substance which conduct electricity under certain conditions that means it allow the electrons to flow through them. The conductivity level of semiconductors lie between the conductors and the insulators.

The good examples of semiconductors are silicon, germanium, gallium, and selenium.

In the given options, aluminium, gold are the metals which conduct electricity and concrete is an insulator which do not conduct electricity while the germanium is the good semiconductor.

Hence, the correct option is, (B) Germanium

Principles of Geology

Explanation:

J. Henslow gifted Darwin the first volume of Principles of Geology, written by Charles Lyell. The book explains about the old age of the earth. Accordingly, the slow rate of several geological processes suggests that the earth is very old.

Darwin read the book as the ship was crossing the Atlantic and learned about geological processes occurring over the millions of years. For example, he learned that the earth's surface was not formed by some catastrophic event.

In his book, Lyell explained the slow and gradual geological processes like erosion gave rise to the vast landscapes present on the earth's surface.

Darwin compared the time taken by geological processes to form the earth's surface and reasoned if these millions of years were enough to support the evolution of species.
