Answer:
The correct answer would be dendrites.
Dendrites are short and branched extension extending from the cell body of a neuron.
The branched nature helps them to receive more and more incoming stimuli.
These extensions receive stimuli usually in the form of chemical either from the environment or from the pre-synaptic neuron.
The chemical stimuli are then converted into electrical signals and are sent towards the axon of the neuron via cell body.
