Not attemptedCorrect Answer: (c) 1 and 3
Probiotic preparations typically contain beneficial bacteria (e.g., Lactobacillus, Bifidobacterium) and yeasts (e.g., Saccharomyces boulardii); many of these organisms are normal residents of the human gut, so statement 2 is wrong. Lactobacilli produce the enzyme lactase that helps break down milk sugar (lactose), making statement 3 correct. Hence, only statements 1 and 3 are correct.
