Suppose a record R contains 5 fields named a, b, c, d, e. R7 contains a pointer to the record R. Which instruction performs R2:=R.d? Select one: O a. lea R2,4[R7] O b. load R2,0[R7] O c. lea R2,2[R7] O d. load R2,1[R7] O e. lea R2,3[R7] O f. load R2,5[R7] O g. lea R2,1[R7] O h. lea R2,0[R7] O i. load R2,4[R7] O j. lea R2,5[R7] O k. load R2,3[R7] O l. load R2,2[R7]
