A) The mean is calculated by adding all the numbers and dividing by the total number of numbers. In this case, (1+2+3+4+5+6+7)/7 = 4.0, so the mean is 4.0.
B) The median is the middle value when the numbers are listed in order. In this case, the middle value is 4.0, so the median is 4.0.
C) Mode refers to the value that appears most frequently. In this case, no value appears more than once, so there is no mode.
Therefore, all the statements are correct, and the best choice is D.
