Assertion (A) : The reciprocal lattice of a fcc is a direct lattice of bcc.
Reason (R) : The reciprocal lattice of a bcc is a direct lattice of fcc.
In the light of the above statements, choose the most appropriate answer from the options given below :
Assertion (A) states that the reciprocal lattice of a face-centered cubic (fcc) structure is a body-centered cubic (bcc) direct lattice.
Reason (R) states that the reciprocal lattice of a body-centered cubic (bcc) structure is a face-centered cubic (fcc) direct lattice.
Both Assertion (A) and Reason (R) present true statements regarding the relationship between direct and reciprocal lattices of fcc and bcc structures.
While both statements are factually correct, the truth of Reason (R) (reciprocal of bcc is fcc) does not serve as an explanation for the truth of Assertion (A) (reciprocal of fcc is bcc). They are independent, albeit related, crystallographic facts.
Therefore, both statements are correct, but Reason (R) is not the correct explanation for Assertion (A).
The most appropriate answer is: Both (A) and (R) are correct but (R) is not the correct explanation of (A).
Morgenthau's principles of political realism are:
A. Politics is rooted in permanent and unchanging human nature which is basically self centred, self-regarding and self-interested
B. Politics is an autonomous sphere of action and cannot therefore be reduced to morals
C. International Politics is an arena of conflicting self-interests
D. The ethics of international relations is situational ethics which is very different from private morality
Choose the correct answer from the options given below:
