The correct option for the phenotypic ratio in this case is the following
9 : 6 : 1  
Explanation:
In order to calculate the ratio, divide the two larger numbers each by the smallest one - which here would be 17.
So, 147 ÷ 17 = 8.7 (rounded off to 9)
And 93 ÷ 17 = 5.6 (rounded off to 6) 
This way, '17' is considered as 1. Hence,
Gold : silver : bronze
    9   :     6   :    1
