The correct option regarding the domain and the range of the function is given by:
A. The domain is (-∞, ∞), and the range is (k, ∞).
An exponential function is given in the function, which has no restrictions, hence the domain is (-∞, ∞).
The range depends of the vertical shift given by k, hence it is given by (k, ∞).
