Given the s-Table and the pseudo-code to construct the optimal solution for the product of the six matrices, select the correct optimal ordering produced: s-Table 2 4 6 A2 2 2 4 4 6 2 def print_optimal_parens (s, i,j print ("A"+str (i+1),end 6 else: print C",end print_optimal_parens (s,i, si1) print optimal _parens , i, j) print (",end- 10 Select one: b. ((Ai ((A2A3))((A4A5A6)) O c. ((A1A2)A3))(A4(A5A6))) d. ((A1((A2A))(A4(ASA6))
