When the concentration gradient of such molecules is high on the either the cytoplasmic side or the extracellular side of the cell. When the concentration gradient is high it flows freely through the cell membrane to the other side without expanding energy.
Hope i helped!
The correct option is D.
Neurotransmitters categorized as inhibitory are expected to hyperpolarize the membrane.
At inhibitory synapses, release of neurotransmitters causes inhibitory postsynaptic potentials or IPSP, which is a hyperpolarization of the presynaptic membrane.
Actually, depolarization and hyperpolarization occurs on neuron when an ion channel in the membrane open or close which can alter the ability of certain types of ions which enter from or exit out of the cell.
Neurotransmitters which is inhibitory have inhibitory effects on the neuron as it means they can decrease the possibility that the neuron will tend to fire an action. Modulatory neurotransmitters can also affect various neurons at the same time which results in the influencing effects of other chemical messengers.
Inhibitory neurotransmitter somehow decreases the action potential of the neuron. When the action potential falls below a certain level which is called threshold potential, the neuron will not be able to generate action potentials and thereby unable to exit the nearest neurons.
So, neurotransmitters are in general expected to hyperpolarize the membrane in some extent.

The given statement is true.
Explanation:
Research work needs to be conducted in some particular, well-organized processes. This systematic process aims at gathering ample of information to reach a conclusion by the researcher.
It includes-
(i) identification of a problem to raise a question on that;
(ii) reviewing that problem and learning all about it;
(iii) clarification of the problem is needed which make the scope of study narrow;
(iv) defining the concepts and terms of the research;
(v) studying a particular group which is the objective of the research; (v) The methods and participation is reviewed;
(vi) Collection of data is needed;
(vii) analyzing the data is the last step.
