Let A = { < C,D,w > | C and D are DFAs and w is a string such that ...}. Suppose we are trying to construct a Turing machine M that decides A as follows:

M = "On input C,D,w:

1. Do something
2. Do some other things"

What is wrong with the above TM M?

	a.	The input format is incorrect. It should be .
	b.	Need an explanation about what are C, D, and w.
	c.	Nothing wrong with TM M.
	d.	Both a and b.

b.
