Answer:
a. increases information overload
Explanation:
Gaining information usually improves decision making since more facts and situations get revealed owing to which there is better comprehension, analysis and decision making.
But, beyond a saturation point i.e the level beyond which an individual's mind cannot take any further information or process it, such gain of information results into an overload which leads to confusion and hampers the decision making process.
At the same time, when such a saturation point gets breached, the cost of providing such an information also increases which makes it unproductive.
