The speech-thought differential is the difference between how fast you think and how fast the speaker talks.
This "thought-speech gap" or "listening gap" means that the brain has extra capacity and WILL process information using that extra capacity. For example, a listener can process a lot of non-verbal cues. Great listeners will observe such cues and use them to guide the conversation to fit their communication goals.
But the difference in how quickly people speak and how quickly they listen also creates an opportunity for the brain's cognitive biases to operate and shape the listener's perception. I've written before about some of the cognitive biases that can occur especially when listening. See the Listen Like a Lawyer blog posts here and here and here on cognitive biases such as the well-known confirmation bias.
Hence, the correct answer is Option A.
