Solution
The correct option is B Birds
Preen gland, also known as Uropygial or Oil gland, in birds, is an organ located on the back near the base of the tail. Paired or in two united halves, it is found in most birds except in some like ostrich, emu etc. The secretions of the preen gland empty to the skin surface through one or more nipplelike pores. The oil is thought to help preserve the integrity of feather structure and, in some species, is also believed to be useful in preserving the horny structure of the bill and the scales of the legs and feet. Hence, option B is correct.
