Step-by-step explanation:

according to me the answer should be option (b)

given BD= 4 and CB = 12

So BD/CB = 1/3

AB =

 \sqrt{3 \times 3 + 4 \times 4}  \\   \\  \sqrt{9 + 16 }  =   \sqrt{25}  = 5

AC =

 \sqrt{12 \times 12 + 5 \times 5}  =  \sqrt{144 + 25}  =  \sqrt{169} = 13

so sin theta = AB / AC = 5/13
