Villi are small finger like folding in small intestine. Villi produce numerous microscopic projections called microvilli. Hence option a is true.

Microvilli increase the surface area enormously. So option b is true.

Villi are supplied with a network of capillaries and a large lymph vessel called the lacteal. So option c is true.

So option d is not true. Digestion of all nutrients is completed in intestine and not fat alone.

Hence the correct answer is option (d).
