The correct answer is that the maximum allowable concentration of Ethylmorphine under Schedule III is 15mg per 5ml. Ethylmorphine is classified as a narcotic and is regulated due to its potential for abuse. The law establishes specific concentration limits for various narcotic substances, and for Ethylmorphine, this limit is set at 15mg per 5ml.

The other options do not align with the defined regulatory limits for Ethylmorphine under Schedule III. A concentration of 1mg per 5ml is too low and does not reflect the legal maximum. The choices of 18mg and 5mg per 5ml also fall outside the specified guidelines, with 18mg exceeding the maximum allowable amount. Hence, the optimum and legally permissible concentration of Ethylmorphine in a liquid formulation is established as 15mg per 5ml.
