Answer:
A. He walked to town to the nearest gas station.
Step-by-step explanation:
Since he had a full bottle of water and was less than a mile away from town, he could walk to town and not be dehydrated by doing so. He couldn't of flagged down another motorist because he had not seen any other cars in the past hour and he had a spare tire but it was flat probably becuase something in his trunk popped it. Also, he couldn't of called a tow truck if his phone's battery was dead so A. He walked to town to the nearest gas station is definitely the right answer.
