• order of the reaction can be zero, positive and fractional.
• order is an experimentally determined quantity.
• order of  reaction is not always equal to sum of stoichiometric coefficients of balanced equation for a reaction. As sometimes it can vary because of being experimentally verified.So, option 'c' is incorrect.

Answer 2

Explanation:

During the course of the reaction shown below, reactants A and B are consumed while the concentration of product AB increases. The reaction rate can be determined by measuring how fast the concentration of A or B decreases, or by how fast the concentration of AB increases.
