In Grid representation, in a translational scan the mobile molecule B moves through the grid representing the static molecule A and a signal describing shape complementarity, fc, is generated for each mapping. Mathematically the correlation function, fc, of fA and fB is given by ______ where N is the number of grid points along the cubic axes i, j, and k and α, β, and γ are the translational vectors of the mobile molecule B relative to the static one A.

• A. fc = \(\sum_{i=1,j=1,k=1}^N\) (fA,i,j,k * fBi+αj+βk+ɣ)
• B. fc = \(\sum_{i=0,j=0,k=0}^N\) (fA,i,j,k * fBi+αj+βk+ɣ)
• C. fc = \(\sum_{i=1,j=1,k=1}^N\) (fA,0,0,0 * fBi+αj+βk+ɣ)
• D. fc = \(\sum_{i=0,j=0,k=0}^N\) (f0,i,j,k * fBi+αj+βk+ɣ)
