From the options given below, select the option which DOES NOT contain correct isotopes of the elements. A. O -->  16O8 , 17O8 , 18O8 B. C --> 13C6 , 14C6 , 15C6 C. S --> 31S16 , 32S16, 33S16, 34S16 D. U --> 233U92 , 235U92 , 238U92 Correct Answer B and C

  • The isotopes of Sulphur and Carbon are given incorrectly.
  • Isotopes of Carbon : 12C6 , 13C6 , 14C6
  • Isotopes of Sulphur : 32S16 , 33S16, 34S16, 35S16
  • Atoms of the same element that contain same number of electron but different number of neutrons are termed as Isotopes. Thus, isotopes have same Atomic Number but different Mass Number.

Consider the following two C code segment. Y and X are one- and two-dimensional arrays of size n and n × n respectively, where 2 ≤ n ≤ 10. Assume that in both code segments, elements of y are initialized to 0 and each element X[i] [j] of array X is initialized to i + j. Further assume that when stored in main memory all elements of x are in same main memory page frame. Code segment 1:                 //initialize elements of y to 0                 //initialize elements X[i] [j] of X to i+j                       for (i = 0; i < n; i++)                                 Y[i] += X[0] [i]; Code Segment 2:                 //initialize elements of Y to 0                 //initialize elements X[i] [j] of X to i+j                        for (i = 0; i < n; i++)                                 Y[i] += X[i] [0]; Which of the following statements is/are correct? S1: Final contents of array Y will be same in both code segments S2: Elements of array X accessed inside the for loop shown in code segment 1 are contiguous in main memory S3: Elements of array X accessed inside the for loop shown in code segment 2 are contiguous in main memory
