A physical quantity \( A \) is related to four observations \( a, b, c \) and \( d \) as follows, \( A=\frac{a^{2} b^{3}}{c \sqrt{d}} \). The percentage errors of measurement in \( a, b, c \) and \( d \) are \( 1 \%, 3 \%, 2 \% \) and \( 2 \% \) respectively. What is the percentage error in the quantity \( A \)
[Kerala PET 2005; NEET 2013]
(a) \( 12 \% \)
(b) \( 7 \% \)
(c) \( 5 \% \)
(d) \( 14 \% \)
