In a cymose inflorescence, the oldest flower opens first, indicating which developmental pattern?

Explanation:
In cymose inflorescences, the oldest flower opens first because the terminal bud matures first and then lateral buds below take turns blooming. This creates a maturation sequence from the apex down toward the base, which is described as basipetal development. So the pattern shown is basipetal, with flowers opening from the top and progressing downward. If it were acropetal, the progression would go from base toward the apex; simultaneous would mean all flowers open together; random would lack any orderly direction.
