Could you tell me what the difference is between (A) and (B) in the following sentence? Thank you in advance.
Please do not allow the child who is aged under 8 [ (A) to use / (B) using ] the elevator alone.
"Allow" permits an infinitival complement but not a gerund-participial one. So "to use the elevator alone" is fine but not *"using the elevator alone".

B is incorrect grammar.
I'd say eg Please do not allow any child under 8 to use the elevator alone.
