Final answer:
The words 'complacent' and 'compliant' are neither similar nor contradictory, as they refer to different behaviors: self-satisfaction and conforming to rules, respectively. Option C is the correct answer.
Step-by-step explanation:
When examining the words complacent and compliant, their meanings are neither similar nor contradictory. The word complacent typically means being self-satisfied, often without awareness of potential dangers or defects. In contrast, compliant refers to the act of conforming to a rule, standard, or instruction. Therefore, someone can be compliant with rules without being complacent about the risks or issues at hand. Additionally, one could be complacent and yet not compliant if they are so self-satisfied that they ignore rules or best practices.
Given this context, the correct answer to the question is C: Neither similar nor contradictory, since these words describe different attributes or behaviors that don't necessarily oppose or mirror each other.
