the correct option is c.
mean=sum of observation/no of observations
mean=8+4+12+10+6+6+25/7=71/7=10.1
mode=6 ,evidently
median=first arrange the observations in ascending order .then the middlemost observation is the median
4,6,6,8,10,12,25 now you can see the median is 8.. or using the formula
median =n+1/2=8/2=4th observation which is 8
