An air bubble of radius 1 cm rises with terminal velocity 0.21 cm/s in liquid column. If the density of liquid is\[1.47\times {{10}^{3}}kg/{{m}^{3}}\]. Then the value of coefficient of viscosity of liquid ignoring the density of air, will be

• A. \[1.71\times {{10}^{4}}poise\]
• B. \[1.82\times {{10}^{4}}poise\]
• C. \[1.78\times {{10}^{4}}poise\]
• D. \[1.52\times {{10}^{4}}poise\]
