Mr. Murugan from Chennai experienced the comfort of Limo during his visit to China. He was willing to deposit an approximate price of Limo to buy the first available unit from Mr. Ahmed, a dealer in Chennai, known for fair dealing. Ginger Automobile is yet to announce the actual price, and the process for allocation of the vehicles. In order to maximise his cash flow, Mr. Ahmed should 1. collect the amount from Mr. Murugan. Later when the delivery is delayed, blame it on PAC's problems. 2. collect 50% as advance and the remaining 50% after the confirmation of launch date by Ginger Automobiles. 3. collect the amount Mr. Murugan is willing to deposit after clarifying that delivery is subject to the company policy. 4. not collect the amount, but suggest to Mr. Murugan to write to Ginger Automobiles. 5. collect the amount and transfer it to the account of Ginger Automobiles, instead of keeping it in his personal account.

A

Only 3

B

1, 2 and 3

C

Only 2

D

All 1, 2, 3, 4 and 5

E
