Answer #1

In case larger the acuity the smaller will be the receptor. If the field is really large then the area wont be as that sensitive because of reason that the receptors will be really spread apart.
Thus when the perception acuity if high you should have more receptors and the sensory neurons are involved.

So for high acuity more receptors and small field is there.
So the answer is option B.
The acuity increases with more receptors and smaller receptive field.

Thank you....
