(B) We know that $\sin^2 	heta + \cos^2 	heta = 1$.First,consider $(\sin^2 	heta + \cos^2 	heta)^3 = 1^3$,which expands to $\sin^6 	heta + \cos^6 	heta + 3 \sin^2 	heta \cos^2 	heta (\sin^2 	heta + \cos^2 	heta) = 1$.Since $\sin^2 	heta + \cos^2 	heta = 1$,we have $\sin^6 	heta + \cos^6 	heta = 1 - 3 \sin^2 	heta \cos^2 	heta$.Next,consider $(\sin^2 	heta + \cos^2 	heta)^2 = 1^2$,which expands to $\sin^4 	heta + \cos^4 	heta + 2 \sin^2 	heta \cos^2 	heta = 1$.Thus,$\sin^4 	heta + \cos^4 	heta = 1 - 2 \sin^2 	heta \cos^2 	heta$.Substituting these into the expression:$2(1 - 3 \sin^2 	heta \cos^2 	heta) - 3(1 - 2 \sin^2 	heta \cos^2 	heta) + 1$$= 2 - 6 \sin^2 	heta \cos^2 	heta - 3 + 6 \sin^2 	heta \cos^2 	heta + 1$$= 2 - 3 + 1 = 0$.

The value of $2(\sin^6 \theta + \cos^6 \theta) - 3(\sin^4 \theta + \cos^4 \theta) + 1$ is
