Which of these phrases is an example of ''Camel case''?

Camel case is the practice of writing phrases without spaces or punctuation, indicating the separation of words with a single capitalized letter, and the first word starts with either upper or lower case. Common examples are ''iPhone'' and ''eBay'', or multi-word domain names ''EasyWidget Company.com''. Some programming styles prefer Camel case with first letter capitalised (XH TML max ID). Classes should be named in upper Camel case: MyFairLady. Some people and organizations, notably Microsoft use the term Camel case only for lower Camel case: ''backcolor''. In uppercase, the identifier are capitalized for two or fewer letters: ''System.IO, System.Web.UI''.

Camel case is distinct from Title case, which capitalises all words but retains the spaces between them: ''Publication Manual'', and from Tall Man lettering which uses capitals to emphasize the differences between similar-looking product names such as ''predniSONE'' and ''predniSOLONE''. Camel case is also distinct from Snake case which uses underscores: ''C++, Boost''. A study found that Camel case indentifiers could be recognised with higher accuracy. Other examples: Sodium Chloride, NaCl to be written without spaces, abbreviation for instance ''Et'' for ''ethyl'', CO2 as ''Dry Ice'', PolyGram (1972), formerly Gramophone-Philips Group. MasterCard (1979), formerly MasterCharge, SportsCenter (1979).
