(c)
Utricularia
(d)
All the above
Correct answer: (a) 
Solution: 
The members of family Orchidaceae have an undifferentiated embryo in which plumule, radicle and cotyledon is absent. The embryos of orchids are very minute in size. In such plants, the seeds are formed without undergoing embryogenic differentiation. The globular structure divides and after attaining some size differentiates to form roots and shoots. Hence, embryo without plumule, radicle and cotyledon is found in Orchids.
So, the correct answer is A.
