Step 1: Understanding the Question:
This is the first match of the league, against Team C, whose top 5 batsmen average 270 runs, the highest of any opposing team. So Team A needs its strongest possible batting group for this match. We must again pick the 5 of the 10 listed batsmen that gives A the best chance of winning.
Step 2: Key Formula or Approach:
As before, add up each option's 5 batsmen's career averages to estimate expected runs, then check the average percentage dismissed below 20 to estimate how risky the line-up is. The group with the highest combined average and the lowest combined failure rate is the safest pick against a strong opponent like C.
Step 3: Detailed Explanation:
Recall the averages: RD 40, ST 44, SG 41, VS 31, RU 28, YS 35, VV 35, MK 30, MT 36, MD 45. Add up the average of each option's 5 batsmen:
Option A, RD + ST + SG + MD + YS: \(40+44+41+45+35=205\)
Option B, VS + YS + RU + MD + MT: \(31+35+28+45+36=175\)
Option C, RD + ST + SG + VS + MD: \(40+44+41+31+45=201\)
Option D, YS + RU + VS + MK + MD: \(35+28+31+30+45=169\)
Option E, ST + VS + RU + MD + SG: \(44+31+28+45+41=189\)
Option A has the highest combined average, 205 runs, just ahead of C at 201, and well ahead of E, B and D, all below 190. Options B and D both include RU, whose average of 28 is the lowest of the ten batsmen, so they cannot be Team A's strongest possible group.
Between A and C, check the failure rate. For A: RD 20, ST 20, SG 25, MD 30, YS 40, which averages to \(\frac{20+20+25+30+40}{5}=27\%\). For C: RD 20, ST 20, SG 25, VS 50, MD 30, which averages to \(\frac{20+20+25+50+30}{5}=29\%\). A is both slightly stronger on average and slightly safer than C, since C swaps YS (average 35, only 40 percent risk of falling under 20) for VS, who is dismissed below 20 in half of his innings. So A edges out C on both measures.
Step 4: Final Answer:
Option A, RD, ST, SG, MD, YS, has the highest total career average (205) and a lower failure rate than its closest rival C, so it gives Team A the best chance of winning its opening match against the strong Team C line-up. As with the earlier question in this caselet, the official XAT key marks this question's data as ambiguous with no fixed correct option; the calculation above identifies the strongest supported choice.
\[ \boxed{\text{Option 1: RD, ST, SG, MD, YS}} \]
