Which one of the following is a common mixer for cocktails?

Orange juice is a common mixer for cocktails primarily due to its versatility and the refreshing flavor it provides. It complements a wide range of spirits, enhancing the overall taste of cocktails while adding a sweet and tangy profile. In classic cocktails, such as the Screwdriver, which combines vodka and orange juice, the mixer plays a crucial role in balancing the alcohol content with a more palatable flavor.

Additionally, orange juice can be used in various cocktails, from mimosas at brunch to more complex drinks. Its popularity as a mixer stems from both its flavor and the ease of integrating it with different types of alcohol, making it a staple in many bars and home mixology. In contrast, the other options are either straight alcohols or do not serve the function of a mixer.
