1:

The incorrect sentence with comma usage is C: "Your shoes, by the way are not formal enough for tonight's dinner." The correct version should be "Your shoes, by the way, are not formal enough for tonight's dinner." The comma should be placed after "by the way" to set off the interrupter.

2:
The incorrect sentence with comma usage is A: "For example the basset hound is a breed that makes a strange-sounding bark." The correct version should be "For example, the basset hound is a breed that makes a strange-sounding bark." The comma should be placed after "example" to indicate the introductory phrase.

3:
The incorrect sentence with comma usage is C: "Needless to say heat from the sun costs nothing." The correct version should be "Needless to say, heat from the sun costs nothing." The comma should be placed after "say" to separate the introductory phrase.
