Applying many controls without sufficient evaluation increases operating costs and disrupts business workflows is the correct answer.

Deploying a large set of controls without adequate evaluation can create complexity that raises ongoing operational and maintenance costs. It can also introduce friction for users and systems which leads to broken or slowed business processes and higher support overhead.

Excessive or poorly tuned controls often generate false positives and alert fatigue which consume analyst time and can hide real threats. They also increase the chance of interrupting legitimate workflows which reduces productivity and may force teams to seek workarounds that introduce new risks.

Short term improvement in end user satisfaction is incorrect because adding many controls usually does not improve user satisfaction. In most cases it increases friction or causes confusion which can reduce user satisfaction rather than improve it.

Google Cloud Security Command Center is incorrect because that option names a specific product and not a negative consequence of deploying many controls. The question asks about outcomes of control deployment and not about a vendor service.

Complete removal of all risk is incorrect because no set of controls can eliminate risk entirely. Controls can reduce risk and manage it to acceptable levels but they cannot provide absolute elimination of risk.
