• A. phototropic
• B. photoperiodic
• C. geotropic
• D. thigmotropic

Answer 1

The correct option is B photoperiodic

Some plants require the exposure to light for a period exceeding a well defined critical duration, while others must be exposed to light for a period less than this critical duration before the flowering is initiated in them. Hence, the flowering process is photoperiodic.

So, the correct option is 'photoperiodic'.
