(1) On Tuesday A and C have an open period from 9:30 a.m to 11:00 a.m.
No information on B and D.
Therefore, Statement (1) alone is insufficient.
(2) On Tuesday D has an open period from 10:30 a.m. to 1:00 p.m. and B has an open period from 8:00 a.m. to 12:00 p.m.[/quote]
No information on A and C.
Therefore, Statement (2) alone is insufficient.
Combining (1) and (2)
A,B,C and D have a common 30 minutes open period - from 10:30 - 11:00
Statements (1) and (2) together are sufficient.
Therefore, answer is C.
