Answer:

A. It is not possible to determine the mass of HD68988 based on the information provided. The mass of a star can be estimated using its luminosity and surface temperature, but these values are not given. Additionally, the mass of a star cannot be determined from the properties of a planet orbiting around it.

B. It is not possible to determine the mass of HD68988 in terms of the mass of our sun based on the information provided.
