What kind of relation can be obtained between first order derivative and second order derivative of an image having a on the basis of edge productions that shows a transition like a ramp of constant slope?

• A. First order derivative produces thick edge while second order produces a very fine edge
• B. Second order derivative produces thick edge while first order produces a very fine edge
• C. Both first and second order produces thick edge
• D. Both first and second order produces a very fine edge
