To write the expression in descending order, we need to arrange the terms based on the exponent of x, from highest to lowest. So the expression can be written as:

-3x^5 - 9x^3 + 6x^2 - x

Now we can see that the coefficients of the terms in descending order are:

-3, -9, 6, -1

Therefore, the correct answer is option d.
