5 integers not necessarily distinct

is Mode = Range ??

Statement 1) SD is 0

1,1,1,1,1

SD=0, but Mode = 1, Range = 0, Answer to the question is No

0,0,0,0,0

SD=0, but Mode = 0, Range = 0, Answer to the question is Yes

Statement 2) At least one number in L is 0

this does't help.

Combine

0,0,0,0,0

SD=0, but Mode = 0, Range = 0, Answer to the question is Yes

Answer C

#1
SD can be 0 ; if the mean of the set is same as other integers
eg 1,1,1,1,1 or 0,0,0,0,0 so in sufficeint
as the mode and range of set wont be same in both cases

#2
one no being 0 wont suffice the relation of getting the mode same as range

from1 & 2
for set which has 0,0,0,0,0 would be correct
