Onestly I don't see the C4 exploding in that panel, not like a bomb explosion. More like a baloon explosion... but I fear that if I'll go on in this discussion I will keep saying again and again the same things. So, my view on the discussion is:
 * Deidara uses Doton to manipulate the clay, making it move or, in the case of the C4, breaking it into little bombs
 * Explosion Release comes in play as the second part, unrelated to the Doton (there is still, though, Deidara's C0 defused by Omoi's Lightning)
 * if the novels are canon, Steel Release is probably Lightning + Earth

That said, I will call out of the discussion unless I'll have something new to add to it ^^
