The options for this question are missing: here are the missing options:
A) S is an infinite set
B) S is the empty set
C) S has exactly one element
D) S is a finite set and has at least two elements.
Answer:
The correct answer is Option: B
x² - y² = 12345678
here R.H.S is even so both x and y should be the odd integers.
But here the different of the square of two odd integers is the multiple of 8 but here the R.H.S is not the multiple of 8.
