    C. 3Pi/2 or 270 degrees

    Step-by-step explanation:

    The first step is to ignore the negative sign and then evaluate the arcsin of 1 to obtain the reference angle of θ in the first quadrant;

    θ = arcsin (1)

    θ = 90 degrees or equivalently pi/2

    Since the sine of θ was given as - 1, this will imply that θ lies either in the third or forth quadrant where the sine of an angle is negative.

    To obtain the value of θ in the third quadrant we simply add 180 degrees of pi radians to our reference angle;

    90 + 180 = 270 degrees

    pi/2 + pi = 3/2 pi
