The correct answer is option 3: Shooting.

Option 1: Table Tennis. This sport involves two players hitting a small ball over a net using a paddle. There is no information or evidence to suggest that Avani Lekhara excels in table tennis, so this option is incorrect.

Option 2: Cycling. This sport involves riding a bicycle, either on the road or on a track. Again, there is no information or evidence to suggest that Avani Lekhara excels in cycling, so this option is also incorrect.

Option 3: Shooting. This sport involves using firearms to accurately hit targets. Avani Lekhara has indeed excelled in shooting, as she won a gold medal in the women`s 10m air rifle standing SH1 event at the 2020 Paralympic Games in Tokyo. This option is therefore correct.

Option 4: Boxing. This sport involves two opponents punching each other while wearing padded gloves. There is no information or evidence to suggest that Avani Lekhara excels in boxing, so this option is incorrect.

In conclusion, Avani Lekhara excels in the sport of shooting, specifically in the women`s 10m air rifle standing SH1 event.
