Read the following statements.

Statement A: All complete flowers are bisexual.

Statement B: All bisexual flowers need not to be complete flowers.

In light of the above statements, choose the correct answer from the options given below. 

Statement A is correct. A complete flower is defined as having all four main floral parts: sepals, petals, stamens, and pistils. Bisexual flowers, also known as perfect flowers, have both male (stamens) and female (pistils) reproductive structures. Therefore, all complete flowers are bisexual.

Statement B is also correct. While all complete flowers are bisexual, not all bisexual flowers are necessarily complete. Some flowers may lack one or more of the four main floral parts (sepals, petals, stamens, pistils) but still contain both male and female reproductive structures. For example, certain wind-pollinated flowers, such as those of some grasses, may lack petals and have reduced or absent sepals, yet they still have both stamens and pistils, making them bisexual.
