D. The correct option is 76 mg.
Ordered dosage =
Patient height = 158.49 cm
Patient weight = 54.43 Kg
Empercial constant = 3600
According to nomogram and mosteller method,
Body surface area $\left({m}^{2}\right)=\sqrt{\frac{158.49×54.43}{3600}}$
Body surface area $\left({m}^{2}\right)=\sqrt{\frac{8623.6}{3600}}$
Body surface area $\left({m}^{2}\right)=\sqrt{2.39}$
Body surface area $\left({m}^{2}\right)=1.54$
