Let n be a positive integer. Which among the following statements is true? * O n+1 and n+ 2 are not relatively prime and lcm(n + 1, n + 2) = n +3. O gcd(n + 1, n + 2) = n+ 1 and lcm(n + 1, n + 2) = n+ 2. %3D None of the mentioned n + 1 and n + 2 are relatively prime and lcm(n + 1, n + 2) = (n+ 1)(n + 2).
