Which of the following shows the correct order of decreasing basicity in aqueous medium -
(A) \( \left(\mathrm{CH}_{3}\right)_{3} \mathrm{~N}\left(\mathrm{CH}_{3}\right)_{2} \mathrm{NH}\mathrm{CH}_{3} \mathrm{NH}_{2}\mathrm{NH}_{3} \)
(B) \( \left(\mathrm{CH}_{3}\right)_{2} \mathrm{NH}\left(\mathrm{CH}_{3}\right)_{3} \mathrm{~N}\mathrm{CH}_{3} \mathrm{NH}_{2}\mathrm{NH}_{3} \)
\( \mathrm{P} \)
(C) \( \left(\mathrm{CH}_{3}\right)_{2} \mathrm{NH}\mathrm{CH}_{3} \mathrm{NH}_{2}\left(\mathrm{CH}_{3}\right)_{3} \mathrm{~N}\mathrm{NH}_{3} \)
(D) \( \left(\mathrm{CH}_{3}\right)_{2} \mathrm{NH}\mathrm{CH}_{3} \mathrm{NH}_{2}\mathrm{NH}_{3}\left(\mathrm{CH}_{3}\right)_{3} \mathrm{~N} \)
\( \mathrm{W} \)
