Which of the following is the recurrence relation for the matrix chain multiplication problem where mat[i-1] * mat[i] gives the dimension of the ith matrix?

A. dp[i,j] = 1 if i=j
dp[i,j] = min{dp[i,k] + dp[k+1,j]}

B. dp[i,j] = 0 if i=j
dp[i,j] = min{dp[i,k] + dp[k+1,j]}

C. dp[i,j] = 1 if i=j
dp[i,j] = min{dp[i,k] + dp[k+1,j]} + mat[i-1]*mat[k]*mat[j].

D. dp[i,j] = 0 if i=j
dp[i,j] = min{dp[i,k] + dp[k+1,j]} + mat[i-1]*mat[k]*mat[j].
