Option B is correct. In England and Wales, section 136 detention begins when the person arrives at the first place of safety and normally lasts for up to 24 hours. The registered medical practitioner responsible for the examination may authorise an extension of up to 12 hours only when the person's condition makes it impracticable to carry out or complete the assessment within 24 hours. The absolute ceiling is therefore 36 hours. Option A reflects the law before the Policing and Crime Act 2017 changes took effect. Options C and D describe detention periods associated with sections 2 and 3 respectively, not the section 136 place-of-safety power. Option E confuses the possible extension period with the initial detention period.
