الإجابة: A. IV calcium chloride
This is symptomatic, severe hypocalcaemia after thyroidectomy (Ca 6.5 mg/dL), so the first step is IV calcium. Oral calcium and calcitriol come later, for maintenance. The sources name calcium gluconate as the IV form; IV calcium chloride is the only IV calcium option offered here.

A
ليش صح
Severe or symptomatic hypocalcemia (here Ca 6.5, below the 7.5 mg/dL cut-off) needs IV calcium first; the source names calcium gluconate as the IV form.

B
ليش غلط
Oral calcium supplementation is for mild or chronic hypocalcemia (no symptoms or only mild irritability); this patient is symptomatic and severely low.

C
ليش غلط
Calcitriol (vitamin D) is supplementary treatment; the first-line therapy in severe cases is IV calcium gluconate, oral calcium is for mild to moderate cases.

D
ليش غلط
For severe cases the source gives IV calcium gluconate; vitamin D (calcitriol) supplementation is a separate, additional step, not the initial treatment of severe symptomatic hypocalcemia.
