Correct answer is Single Section.

Full Face = Complete Face Section at once.
Full face method is exclusively used for tunnel sections of lesser c/s area. The method involves excavation of the whole section at once limited to certain depth in the direction of tunneling. Working of TBM falls under this category.

Excavations are done at the same time in three sections is the right answer.
