Answer:

  C  6

Step-by-step explanation:

The point P is the centroid of the triangle (the intersection of medians). The centroid divides the median into parts in the ratio 2:1, with the longer part between the centroid and the vertex.

Here, that means ...

  NP/PQ = 2/1

  NP = 2·PQ = 2·3

  NP = 6
