Option A is correct. if you uninstall before new package installation then it will lost the content which is not mentioned in new package so we should use force to upload then we can replace new package data along with old data which is not there in new package.

Option A is correct. Option B will only uninstall the package but will not remove the earlier package. So in either of the case, whether Package is installed or uninstalled (not removed), force upload is required.

My thoughts: B Uninstalling Packages AEM lets you uninstall packages. This action reverts the contents of the repository that are impacted to the snapshot made immediately prior to the package installation. NOTE Upon installation, a snapshot package is created containing the content that will be overwritten. This package will be re-installed when you uninstall the package. https://experienceleague.adobe.com/docs/experience-manager-65/administering/contentmanagement/package-manager.html?lang=en#package-share

uninstall creates snapshot (or am I wrong?). Once fresh package installed, snapshot package can be installed. My vote is for B.

B is the correct answer because the question is asking to ensure that only the content from the new package is applied

The question asked specifically for minimal changes, so Option A is right, NOT option B

A is correct.

B is the correct answer

Option B is correct. First uninstall then install package

I always use the option B, is the safety way

I think its option A

D can't be the correct. Web Console don't have option to install package(.zip).

Shouldn't be Option A ?
