The correct option is B Multilocular adipose tissue
The cells of the brown adipose tissue are multilocular. They are smaller than those of white adipose tissue. The nucleus of a mature multilocular adipocyte is in an eccentric position within the cell, but is not flattened as is the nucleus of the unilocular adipocyte, which is white adipose tissue.
Thus, the correct answer is option (B), 'Multilocular adipose tissue'.
