The pollination that occurs in opened flowers is called chasmogamy. It is the most common type of pollination in all types of flowers. Chasmogamy is of two types i.e., self-pollination (autogamy) and cross-pollination. Cross-pollination is of two types i.e., geitonogamy and xenogamy. So, we can say that chasmogamous flowers exhibit both autogamy (self-pollination)and allogamy (cross-pollination). While, in Cleistogamous flower the anthers and stigma lie close to each other with in the closed flowers. When anthers dehisces in the flower buds, pollen grains come in contact with the stigma for effective pollination. Thus, these flowers are invariably autogamous as there is no chance of cross-pollen landing on the stigma.

Explanation:
Cleistogamous flowers:
- Cleistogamous flowers are self-pollinating flowers that never open.
- They are typically small and inconspicuous.
- Cleistogamy is a strategy for ensuring reproduction in situations where pollinators are scarce or unreliable.
- Since the flowers do not open, they cannot be pollinated by external agents such as insects or wind.
- Therefore, cleistogamous flowers exhibit autogamy, which is the process of self-pollination, where the pollen from the anther is transferred to the stigma of the same flower.
- The flowers produce both male and female reproductive organs in close proximity, allowing for self-pollination.
Chasmogamous flowers:
- Chasmogamous flowers are the opposite of cleistogamous flowers. They are open flowers that are typically larger and more showy.
- These flowers rely on external agents such as insects, birds, or wind for pollination.
- Chasmogamous flowers exhibit geitonogamy, which is the process of cross-pollination within the same plant. Pollen is transferred from one flower to another flower on the same plant.
- This allows for genetic diversity and reduces the risk of inbreeding.
Correct statement:
- The correct statement is option 'a': Cleistogamous flowers always exhibit autogamy.
- Cleistogamous flowers are self-pollinating and do not rely on external agents for pollination.
- They produce both male and female reproductive organs in close proximity, allowing for self-pollination.
- Autogamy is the only method of pollination in cleistogamous flowers since they do not open and cannot be pollinated by external agents.
Incorrect statements:
- Option 'b' is incorrect because chasmogamous flowers do not always exhibit geitonogamy. They have the potential for both self-pollination and cross-pollination, depending on the availability of pollinators.
- Option 'c' is incorrect because cleistogamous flowers do not exhibit geitonogamy. They only exhibit autogamy.
- Option 'd' is incorrect because chasmogamous flowers can exhibit autogamy if there is no opportunity for cross-pollination.
Therefore, the correct statement is option 'a': Cleistogamous flowers always exhibit autogamy.
