To determine if the vectors are coplanar, we can find the scalar triple product of the three vectors. If the scalar triple product is zero, then the vectors are coplanar.

The scalar triple product is given by the determinant:

|i 2j 3k|
|2i -j k|
|3i j 4k|

Expanding the determinant, we get:

(1 * (-j * 4k) - (2j * 3k))i + (-i * (2i * 4k) - (3i * k))j + (i * (2j * 3k) - (-j * 3i))k
= (-4j - 6kj)i + (-8ik - 3kj)j + (6ij + 3ik)k
= (-4j - 6kj)i + (-8ik - 3kj)j + (6ij + 3ik)k

For the vectors to be coplanar, the scalar triple product must be zero. In this case, none of the coefficients of i, j, and k are zero. Therefore, the vectors are not coplanar.

The answer is: a) not coplanar.
