Sorry, but there is no effective way to enlarge very small photos like yours and have the quality required for Adobe Stock to accept it. Even with your small image, there are technical issues (colour is over saturated, there are artifacts around the top of the building, uneven exposure and the lines of the building need to corrected to be vertical.) Enlarging your photo to meet the minimum 4 MP requirement, would only exagerate the technical issues.
Ideally, you need to change the settings on your camera and look forward to new photo opportunities and not worry about what is in your existing portfolio if they don't meet today's criteria.
