Put Yes or No for each entry of the table of data dependenci

Put Yes or No for each entry of the table of data dependencies between instructions below in a 5-stage pipeline. The meaning of instructions are shown inline below (Note that these instructions are NOT HACK format but an example format)

            I1: LD R1, MEM(324) /* Load content of MEM(324) into Register R1 */
          I2: ADD R1, R1, R2 /* Add R1 to R2 and store result in R1 */
          I3: SUB R2, R2, R4 /* Subtract R4 from R2 and store result in R2 */
          I4: MUL R3, R3, R2 /*Multiply R3 and R2 and store result in R3 */
          I5: ST MEM(324), R1 /* Store contents of R1 into MEM(324) */
