Answer:
Option (d) outfile.write();
Explanation:
As the object created for the class BufferedWriter is outfile, outfile.write is the correct syntax for writing in a text file. Here, write is the method used for writing into a text file. The data present is written in the textfile. Here, the text file is opened before writing the text into the file. Option (d) is correct.
Option (a) outfile.newLine(); is used to separate the lines. This is used to break the existing lines into smaller lines. This can also be used to start a new line. Here, newLine() is the method.So, option (a) is not suitable.
Option (b) outfile.existLine(); This is not a valid syntax as there is no method called existLine() in the class BufferedWriter. So, this is a wrong option.
Option (c) Write(outfile); This is not a valid syntax for writing in a text file. This is a wrong option.
