Rain is falling vertically with a speed of \( 35 \mathrm{~ms}^{-1} \). Winds starts blowing after sometime with a speed of \( 12 \mathrm{~ms}^{-1} \) in east to west direction. In which direction from vertical should boy waiting at a bus stop hold his umbrella?
(a) \( \tan ^{-1}(0.45) \), west
(b) \( \tan ^{-1}(0.343) \), west
(c) \( \tan ^{-1}(0.343) \), east
(d) \( \tan ^{-1}(0.24) \), east
