Detailed Solution

Concept: A sine wave is a geometric waveform defined by the function y=sinx that oscillates (moves up, down, or side to side) on a regular basis. In other terms, it is a smooth s-shaped wave that oscillates between zero and one. The sine wave is a technical chart analysis technique that uses complex mathematics to determine if a market is trending or in a cycle phase.
Here the sine wave A has a positive going zero crossing at 45 and B has a positive going zero crossing at 60. So, A crosses zero first and B crosses after 15. So the sinewave A leads wave B by 15.
Hence , option 1 is correct.
