Six tablets T1, T2, T3, T4, T5 and T6 are placed in a row facing towards North (Not necessarily in the same order). Two tablets are placed between T1 and T5. T3 is placed second to the right of T6. T2 is placed second to the right of T1. T5 is towards the left of T1. Which of the following pair of tablets represents the tablets to the immediate right of T6 and T5 respectively? छह गोलियाँ T1, T2, T3, T4, T5 और T6 को उत्तर की ओर एक पंक्ति में रखा गया है (जरूरी नहीं कि उसी क्रम में)। दो गोलियाँ T1 और T5 के बीच रखी गई हैं। T3 को T6 के दाईं ओर दूसरे स्थान पर रखा गया है। T2 को T1 के दाईं ओर रखा गया है। T5 T1 के बाईं ओर है। निम्न में से कौन सी टैबलेट क्रमशः T6 और T5 के दाईं ओर टैबलेट का प्रतिनिधित्व करती है?
