In an experiment, four quantities \( a, b, c \) and \( d \) are measured with percentage error \( 1 \%, 2 \%, 3 \% \) and \( 4 \% \), respectively. Quantity \( P \) is calculated as follows \( P=\frac{a^{3} b^{2}}{c d} \), percentage error in \( P \) is
(a) \( 14 \% \)
(b) \( 10 \% \)
(c) \( 7 \% \)
(d) \( 4 \% \)
