A source is moving with constant speed \( v_{s}=20 \mathrm{~m} / \mathrm{s} \) towards a stationary observer due east of the source. Wind is blowing at the speed of \( 20 \mathrm{~m} / \mathrm{s} \) at \( 60^{\circ} \) north of east. The source has frequency \( 500 \mathrm{~Hz} \). Speed of sound \( =300 \mathrm{~m} / \mathrm{s} \). The frequency registered by the observer is approximately
(a) \( 541 \mathrm{~Hz} \)
(b) \( 552 \mathrm{~Hz} \)
(c) \( 534 \mathrm{~Hz} \)
(d) \( 517 \mathrm{~Hz} \)
