In Infosys, with spot at 2140, there is a possible mispricing in calls close to money that the trader could hope to exploit. A bull-spread with long 2130c (31.95) versus short 2160c (19.55) costs about 12.5. Since the 2130c is already in the money, the trader effectively pays 2.5 for an upside of 17.5.
In Satyam, with spot at 442.7, a long 440c (8.3) versus short 450c (3.85) costs 4.45 with a maximum pay off of 5.55. Since the long 440c is already in the money, the effective equation is a down payment of 1.75 for a possible return of 5.5.
In TCS, with spot at 1169.65, a long 1170c (12.55) versus short 1200c (3.15) costs 9.4. The maximum pay off is 20.6, which is a reasonable but not tempting ratio because of the expiry factor.
