To have at least 130 subnets, we need to use a subnet mask that can accommodate at least 7 bits for the subnet part. The next available subnet mask with at least 7 bits for the subnet part is /25 or 255.255.255.128, which provides for 128 subnets. However, this is not sufficient for the required 130 subnets. The next available subnet mask with at least 8 bits for the subnet part is /24 or 255.255.255.0, which provides for 256 subnets. This is sufficient to accommodate the required 130 subnets and also allows for more subnets in case of future expansion. Therefore, the best choice is C) 8.
