  • A) None of the above
  • B) Only conclusion I is true
  • C) Either conclusion I and II is true
  • D) Both conclusion I and II are true 
  • E) Only conclusions II is true
Solution
B
Some apartments are flats (I) + Some flats are buildings (I) = I + I = No conclusion follows but possibility exists because the statement are positive. Hence, conclusion I follows.
 
As statements II and III are positives therefore, conclusions II and III  do not follow.

Hence, option B is correct.
