The correct answer is (D) However
Step-by-step explanation:
In sentences or texts, the best way to show the relationship between different ideas or sentences is through transitions or signal words. Additionally, signal words can be of different types depending on whether they show contrast, addition, order, etc. Due to this, if you want to signal contrast, the most effective way is to use transitions that show contrast, this includes words such as but, although, instead and however. Therefore, from the options "however" is the most appropriate word. Also, words such as "similarly" or "same" are used to signal comparison, while the word "also" is used for addition.
