Statement II: The symbol for lead is derived from the name Latin root, in English which means ‘plumbing’.
A.Statement I and statement II is true, and statement II is a correct explanation of statement I
B.Statement I and statement II is true, and statement II is not a correct explanation of statement I
C.Statement I is false and statement II is true
D.Statement I is true and statement II is false
E.Both Statement I and statement II are false

Answer 1

Hint: First of all we know that lead is the element that is derived from the Latin name plumbum. Lead has an atomic number eighty-two. So we need to know the symbol of the element lead and then after examine the two statements and arrive at the correct answer

Complete step by step answer:
We know that lead is a chemical element with the symbol Pb.it is a heavy metal that is denser than most of the common metals. Thus the statement that the symbol for element lead is Pb is correct.
So the statement one is correct.
The lead was then used in making water pipes.
The Latin word for the metal plumbum is derived from the word plumbing.
The symbol Pb for lead is an abbreviation of the Latin word for lead, plumbum which means liquid silver or used as waterworks.
So the statement II is not correct.
Therefore statement one is true and statement two is false.
Hence, the correct option is D.

Additional information: Lead is a heavy metal that is denser than most materials. It is easily extracted from the ores and galena is one main ore of Pb which contains silver. The lead was used for making pipes before and sheets of lead were used as writing tablets.

Note:
The Latin root of the word plumbum in English does not mean plumbing it means liquid silver. The name comes from when lead was widely used as in the construction of water pipes. Also a chemical symbol is the short notation derived from the scientific name of a chemical element like Au for Aurum and Na for Natrium.
