0\( \triangle A B C \) में, \( \angle C=90^{\circ}, a=3, b=4 \) तथा बिन्दु \( D \) भुजा \( A B \)
पर इस प्रकार है कि \( \angle B C D=30^{\circ} \), तो \( C D \) की लम्बाई है-
(A) \( \frac{3}{3+4 \sqrt{3}} \)
(B) \( \frac{6}{3+4 \sqrt{3}} \)
(C) \( \frac{12}{3+4 \sqrt{3}} \)
(D) \( \frac{24}{3+4 \sqrt{3}} \)
