Final answer:
Pánfilo de Narváez was sent to Veracruz to arrest Cortés for his disobedience of government orders.
Step-by-step explanation:
Narváez was sent to Veracruz to arrest Hernán Cortés for his disobedience of government orders. Cortés had been tasked with exploring the lands on behalf of Spain but was later ordered to halt his expedition by the governor of Cuba. Ignoring these orders, Cortés not only continued his mission but also took drastic actions such as burning his ships to prevent retreat and eventually taking Emperor Montezuma II hostage, which further affirmed his disobedient actions. This led to Narváez's mission to arrest Cortés for defying the direct orders of his superiors. The correct option to describe his actions would therefore be option 3: Disobedience.
