Question
Assertion : Sometimes nonsmokers are prone to lung cancer.
Reason : Nonsmokers are also called passive smokers.
- If both assertion and reason are true and the reason is the correct explanation of the assertion.
- If both assertion and reason are true but reason is not the correct explanation of the assertion.
- If assertion is true but reason is false.
- If the assertion and reason both are false.
The correct answer is: If both assertion and reason are true but reason is not the correct explanation of the assertion.
Indoor atmospheres and other confined spaces are often contaminated by tobacco smoke which is inhaled involuntarily by both smokers and nonsmokers. It is called involuntary smoke inhalation or passive smoking. It is now recognized as a cause of lung cancer in nonsmokers.

Copper is the most noble of the first row transition metals and occurs in small deposits in several countries. Ores of copper include chalcanthite (CuSO4 ,5H2O), atacamite 
cuprite (Cu2O), copper glance (Cu2S) and malachite 
However, 80% of the world copper production comes from the ore of chalcopyrite (CuFeS2). The extraction of copper from chalcopyrite involves partial roasting, removal of iron and self-reduction. Iron is removed from chalcopyrite as
