In the following questions a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the following choices. Assertion and reason both are correct statements and reason is correct explanation for assertion Assertion and reason both are correct statements but reason is not correct explanation for assertion. Assertion is correct statement but reason is wrong statement. Assertion is wrong statement but reason is correct statement. Assertion:Total numbr of octahedral voids present in unit cell of cubic close packing including the one that of present at the body centre is four Reason: Besides the body centre there is one octahedral void present a the centre of each of the six faces of the unit cell and each of the which is shared between two adjacent unit cells.
