Answer 1

Answer: (D)

(a) Sun rises or moon sets is an "exclusive or" statement as sun rises and moon sets during day time.
(b) Since all integers cannot be both positive as well as negative. Therefore statement is "exclusive or"
(c) It is not possible for two lines to intersect and parallel at the same time so this statement is "exclusive or" statement.
(d) It is fact that school is closed on holiday as well as on Sunday. Hence the statement is an "inclusive or" statement.
