~~~~~~~~~~~~~~~~~~~~~~~
For brevity, I will use notations C, M, L and T for cities and "c" (coins), "s" (stamps), "b" (books) and "e" (baseball) bor collectors/collections.
(1) From (A), "b" was not in M; "b" was in August.
(2) From (B), "e" was not in L, and "c" was not in T and "c" was not in M.
(3) From (C), "c" was not in C. C was in October. "c" was not in C.
(4) From (D), "s" was not in M.
Looking in this info (1) -(4), we see that neither "b", nor "c", nor "s" was in M.
It leaves only one possibility for M : M = "e". (*)
Next, from (2) "c" was not in T; from (3), "c" was not in C; from (*), "c" was not in M.
It leaves only one opportunity for "c" : "c" = L.
Next, from (A) "b" was not in M; from (1) and (3), "b" was not in C.
It leaves for "b" only one opportunity "b" = T.
Finally, it remains only one opportunity for "s" : "s" = C.
ANSWER. "e" = M (baseball convention was in Mandaue)
"c" = L (coins convention was in Lapu-Lapu)
"b" = T (books convention was in Talisay)
"s" = C (stamps convention was in Cebu).
Solved.
