Answer Details

The underlined word "accelerate" means to increase the speed or rate of something. To find the opposite of this meaning, we need to look for a word that means to slow down or decrease the speed of something. Among the options given, the word that is opposite in meaning to "accelerate" is "retarded" (option B). Therefore, the correct answer is "retarded." It is worth noting that "retarded" is not commonly used in modern English as it can be considered offensive and derogatory. A more appropriate and commonly used antonym for "accelerate" would be "retard" or "slow down."
