And the answer is, over here.

These 4 data points are associated with C1, so we can safely ignore all the other ones.

This one over here would be at the center of the 3 data points over here,

but this one pulls back this data point drastically towards it.

This is about the best tradeoff between these 3 points over here that all have a string

attached and pull in this direction, compared to this point over here.

Any of the other ones don't even lie between those points,

and therefore won't be good cluster centers.

The one over here is way too far to the right.
