The answer and the reasoning

C. Intradermal botulinum toxin injections

Primary focal hyperhidrosis is first managed with topical aluminium chloride hexahydrate. If this fails, intradermal botulinum toxin blocks cholinergic sweat gland stimulation for several months, while iontophoresis suits palms and soles. Oral anticholinergics and sympathectomy are later options.
