Final Answer :
C
Explanation :
Martin's preferences are such that he always substitutes two units of good 2 for one unit of good 1. The only utility function that does not reflect this is option C, which creates a function where the minimum value of either 4 units of good 1 or 2 units of good 2 is used to determine overall utility.
