The Oriental cockroach typically measures between 20-27 mm in length, which aligns with the choice selected. This dimension for the Oriental cockroach distinguishes it from other common pest species. Understanding the size is crucial for identification and management purposes in pest control since it provides a clear reference for pest professionals to determine if they are dealing with this specific type of roach.

The other options present sizes that do not accurately reflect the actual size of the Oriental cockroach. For example, the range of 4-7 cm (which equates to approximately 40-70 mm) is too large, and other measurements like 10-15 mm (1-1.5 cm) are significantly shorter than the insect's actual size, failing to adequately represent this species. When handling infestations, having the correct identification and size parameters is essential for effective control strategies.
