Let the product of $$\omega_1 = (8 + i)\sin\theta + (7 + 4i)\cos\theta$$ and $$\omega_2 = (1 + 8i)\sin\theta + (4 + 7i)\cos\theta$$ be $$\alpha + i\beta$$, $$i = \sqrt{-1}$$. Let p and q be the maximum and the minimum values of $$\alpha + \beta$$ respectively.
Write the two complex numbers as
$$\omega_1 =(8+i)\sin\theta +(7+4i)\cos\theta ,\qquad
\omega_2 =(1+8i)\sin\theta +(4+7i)\cos\theta .$$
Their product is
$$\omega_1\omega_2
=(8+i)\!(1+8i)\sin^2\theta
+\big[(8+i)(4+7i)+(7+4i)(1+8i)\big]\sin\theta\cos\theta
+(7+4i)(4+7i)\cos^2\theta .$$
Compute the four required products one by one.
1. $$AC=(8+i)(1+8i)=65i.$$
2. $$AD=(8+i)(4+7i)=25+60i.$$
3. $$BC=(7+4i)(1+8i)=-25+60i.$$
4. $$BD=(7+4i)(4+7i)=65i.$$
Hence
$$AD+BC=(25+60i)+(-25+60i)=120i.$$
Substitute back:
$$\omega_1\omega_2 =65i\sin^2\theta+120i\sin\theta\cos\theta+65i\cos^2\theta.$$
Factor $$65i$$ in the first and last terms and use $$\sin^2\theta+\cos^2\theta=1$$:
$$\omega_1\omega_2 =65i+120i\sin\theta\cos\theta.$$
Convert the mixed term with $$\sin2\theta=2\sin\theta\cos\theta$$:
$$\omega_1\omega_2 =65i+60i\sin2\theta.$$
Therefore the product is purely imaginary. Write
$$\omega_1\omega_2=\alpha+i\beta,$$
so that $$\alpha=0,\quad \beta=65+60\sin2\theta.$$
The required sum is $$\alpha+\beta=\beta=65+60\sin2\theta.$$
Because $$-1\le\sin2\theta\le1,$$ the maximum and minimum values are
$$p=65+60(1)=125,\qquad q=65+60(-1)=5.$$
The problem asks for $$p+q,$$ which is
$$p+q=125+5=130.$$
Hence the correct choice is Option B (130).
