I don't know about you, but I'm feeling a bit 'Newton-Raphson' about this whole exam question. It's making my head spin!

Okay, let's think this through. The Newton-Raphson method uses the derivative to iteratively converge to a root, so option B is the way to go.

Hmm, I'm not sure about the error bound. Does the Newton-Raphson method provide an error bound with each iteration? That's news to me.

You know, I always get the Newton-Raphson and the bisection method mixed up. Can someone remind me how the Newton-Raphson method actually works?

Wait, isn't the Newton-Raphson method used for finding roots of continuous and differentiable functions? I'm pretty sure option C is incorrect.

The Newton-Raphson method is definitely based on the Taylor series and the first derivative, so I think option B is the correct answer here.
