Express the sum as a product. If possible, find this product's exact value. \( \sin 285^{\circ}+\sin 15^{\circ} \) Choose the correct answer below. A. \( \sin 285^{\circ}+\sin 15^{\circ}=2 \sin 300^{\circ} \cos 270^{\circ} \) B. \( \sin 285^{\circ}+\sin 15^{\circ}=2 \cos 150^{\circ} \sin 135^{\circ} \) C. \( \sin 285^{\circ}+\sin 15^{\circ}=2 \sin 150^{\circ} \sin 135^{\circ} \) D. \( \sin 285^{\circ}+\sin 15^{\circ}=2 \sin 300^{\circ} \sin 270^{\circ} \) E. \( \sin 285^{\circ}+\sin 15^{\circ}=2 \cos 300^{\circ} \sin 270^{\circ} \) F. \( \sin 285^{\circ}+\sin 15^{\circ}=2 \sin 150^{\circ} \cos 135^{\circ} \)
