The map for F follows, with each of the product terms circled. Each of
the two-literal terms corresponds to two squares on the map (since one
of the variables is missing). The AB term is in the 10 column. The AC term
is in the C 1 row and in the 11 and 10 columns (with a common 1 in the
A position). Finally, the minterm ABC corresponds to one square, in the 01
(AB) column and in the C 0 row.
