Answered by GPT 3.5
B. sqrt6

The magnitude of a vector can be found using the formula ||u|| = sqrt(u dot u). Given that the dot product of u with itself is 18, we can plug this into the formula to find the magnitude of u:

||u|| = sqrt(18)
||u|| = sqrt(3*3*2)
||u|| = 3sqrt2

Therefore, the correct answer is A. 3sqrt2.
