The memory address of fifth element of an array can be calculated by the formula

  1. LOC(Array[5]=Base(Array)+w(5-lower bound), where w is the number of words per memory cell for the array

  2. LOC(Array[5])=Base(Array[5])+(5-lower bound), where w is the number of words per memory cell for the array

  3. LOC(Array[5])=Base(Array[4])+(5-Upper bound), where w is the number of words per memory cell for the array

  4. None of above

A Correct answer
Explanation

The address of any array element is calculated as: Base Address + (Index - Lower Bound) × Word Size. For the 5th element, this is LOC(Array[5]) = Base(Array) + w(5 - lower bound), where w represents bytes per memory cell. Options B and C are incorrect because they omit the word size multiplier or use wrong bounds.
