A substring in programming represents all characters from a string, between two specified indices. Given a variable string called seq, a student writes the following program that will generate all nonempty substrings of seq:for i in range(len(seq)) : # line 1 for j in range(i) : # line 2 print(seq[j:i]) # line 3Which of the following changes make the above program correct?A. Program is correct as it is.B. Change line 1 to: for i in range(len(seq)+1) :C. Change line 3 to: print(seq[j:i+1])D. Change line 2 to: for j in range(i+1) :
