Let P be some predicate. Check the box next to each scenario in which Vn N, P(n) must be true.
P(0) holds and for every natural number k > 0, if P(k) does not hold, then there is some natural
number i < k such that P(i) does not hold.
✓(a)
✓(b)
For every natural number k, if P(k) does not hold, then there is a smaller natural number i < k such
that P(i) does not hold.
✔(c) For every natural number k > 0, if P(i) holds for every natural number i <k, then P(k) holds. x
(d) For every natural number k, if P(i) holds for every natural number i <k, then P(k) holds.
