A sphere contracts in volume by `0.01%` when taken to the bottom of sea `1km` keep. The bulk modulus of the material of the sphere is (Given density of sea water may be taken as `1.0xx10^3kgm^-3`).
A. `9.8xx10^(10)N//m^(2)`
B. `10.2xx10^(10)N//m^(2)`
C. `0.98xx10^(10)N//m^(2)`
D. `8.4xx10^(10^)N//m^(2)`
