Here the null and alternative hypothesis are
Null hypothesis H0 : Mean is grater than equal to 32 miles per gallon
Alternative hypothesis is H1: Mean is less than 32 miles per gallon
The type I error is Reject null hypothesis when null hypothesis is true
So the type I error is "Fail to reject the claim that the mean is less than 32 miles per gallon when it is actually greater than 32 miles per gallon"
So option B is correct
