Subject :NSO    Class : Class 8

Read the given statements and mark the correct option.
Statement 1 : Copper sulphate solution is a good conductor of electricity.
Statement 2 : Conduction of electricity takes place in liquids due to flow of ions.

ABoth statement 1 and 2 are true and statement 2 is the correct explanation of statement 1.
BBoth statement 1 and 2 are true but statement 2 is not the correct explanation of statement 1.
CStatement 1 is true but statement 2 is false.
DStatement 1 is false but statement 2 is true.


Question is very confusing. Statement 2 does not naturally flow from statement 1. statement 2 may have read that "All salts allow flow of ions"
