Answer
Glands, Muscles
Explanation
Reflex actions are automatic responses to certain stimuli, which are processed in the nerve pathways without involving the conscious brain. Effectors are the muscles or glands that put the signals into effect. Effectors are either 'afferent' (incoming signals to the CNS i.e. starting in the periphery, ending in the CNS also known as sensory) or efferent(effectors are organs, tissues, or cells that in response to nerve input results in 'effector' behavior i.e. starting in the CNS, ending in the periphery, leading to an action, also known as motor). In this case, the options 'Glands' and 'Muscles' are correct as they can both put these nerve signals into action.
