Which type of bond is found in many carbon-to-carbon bonds in canola oil, but very few carbon-to-carbon bonds in butter? 1) c–c 2) c=c 3) c=h 4) c–h

The answer is (2) C=C. The butter is saturated fatty acids with only single bond between carbon atoms and has high melting point usually solid at room temperature. The canola oil is unsaturated with many double bonds between carbon atoms and has low melting point.
