It is NFC.

From the UCD:
00B4;ACUTE ACCENT;Sk;0;ON;<compat> 0020 0301;;;;N;SPACING ACUTE;;;;
This is only a <compat> decomposition, so SPACE+COMBINING ACCUTE ACCENT
remains unchanged in NFC.
A more interesting case is that of U+0338 COMBINING LONG SOLIDUS OVERLAY,
which combines with > to give U+226F NOT GREATER-THAN. This can damage XML
