Answer #1

[ explanation:-

option A is false because,

from the information provided, we can not say that he is worst..may be there is some runner who has z score less than him.

option B is true because,

a negative Z score indicates that the value is below the mean.

option C is false because,

a positive z score indicates that the value is above the mean, but in question it is mentioned that the z score for his race time is negative. ]

***in case of doubt, comment below. And if u liked the solution, please like.
