  2. BAll members of the birdwatcher's club have a pair of binocularsCorrect
  3. CAll those who take part in photo-contests are members of the birdwatcher's club
  4. DNo conclusion can be drawn.

Explanation

The first statement says that only those who have a pair of binoculars can become members of the birdwatchers club. This establishes having binoculars as a mandatory condition or a prerequisite for membership. Therefore, every person who is currently a member must necessarily possess a pair of binoculars.
