Q is nothing BUT asking about remainder..
total morsels thrown before the pattern is repeated = 2+3+1 = 6..
so REMAINDER when 2000 is div by 6..
1998 is EVEN and also div by 3, so remainder is 2..

Last 3 of morsels are 1998-1999-2000
so he uses the last of morsel of pattern in 1998 two of the first morsels of the pattern in 1999 and 2000, and the pattern is w, w, W, W, W, R..
ans R-w-w

A cannot be the answer as the pattern doesn't indicate 2 actions of wheat together.
Only option C fits in.

Alternate approach:
Remainder = 2. So, Last 4 actions = Wheat White Rye Wheat

Answer: C


you are absolutely correct in your approach but the highlighted portion is not correct

Yes. You are right. I have taken the actions instead of morsels. Stupid error!!!

'
W1 W2 W3 W4 W5 R ------ 2000/6 = REMINDER = 2

so the token stops at W2

so last 3 will be R W1 W2
