Directions: In the following question a statement is followed by two conclusions. Which of the conclusions can be logically drawn from the statement?

Statement: Among the more highly organised moths the pupa remains in the cocoon, the emergence being entirely left to the imago, while the pupae of the more primitive moths work their way partly out of the cocoon before the final moult begins. Conclusions: (A) Cocoon provides safer environs for better development of the pupa. (B) The more complex the organism, the longer the time its embryo may need for full development.
