E) C OPTIONS, really? That sounds more like a way to negotiate capabilities, not send DTMF. I'm pretty sure the answer is one of the C-based options, but which one...?
D) C NOTIFY sounds like it could work too, but I'm not sure if that's specifically for DTMF tones. Hmm, guess I'll have to think this one through a bit more.
I think the answer is C MESSAGE. Sending DTMF tones is a way to transmit data over a voice channel, and C MESSAGE seems like the most appropriate method for that.
