In a recent poll, residents of a certain community were asked to indicate a preference from among 5 options (Options A-E) for a community development project. Each respondent indicated a unique preferred option and each was asked to indicate whether an option other than his or her preferred option would be acceptable, and if so, which one he or she most preferred. Each respondent who indicated an acceptable option other than his or her
preferred option indicated a unique second preference.
The table shows the distribution of the second preferences, grouped by the respondents' first preferences. For example, among respondents for whom Option D was the first preference, 15.0% indicated that Option E was acceptable and was most preferred when compared to Options A, B, and C.
---------------------------------Second preference
For each of the following options, select Yes if, among the respondents who selected that option as their first preference, the majority indicated that at least one of the other options was acceptable. Otherwise, select No.

We need to be very careful with the wording of the question.
Each respondent indicated a unique preferred option and each was asked to indicate whether an option other than his or her preferred option would be acceptable, and if so, which one he or she most preferred. Each respondent who indicated an acceptable option other than his or her
preferred option indicated a unique second preference.
What does each row give us?
B 30% — 5% 4% 1%
This says that of all the people who chose B as their first preference - say there were 100 such people, 30 chose A as second preference, 5 chose C as second preference, 4 chose D as second preference and 1 chose E as second preference. So 30 + 5 + 4 + 1 = 40 people chose a second preference. What about the other 60 who chose B as first preference? They did not select a second preference.
For each of the following options, select Yes if, among the respondents who selected that option as their first preference, the majority indicated that at least one of the other options was acceptable. Otherwise, select No.
We select "Yes" only if majority of the people (more than 50 out of 100) indicated that at least one of the other options was acceptable i.e. if more than 50 gave a second preference.
A - Only 15% gave a second preference. So majority did not give a second preference.
B - Only 40% gave a second preference. So majority did not give a second preference.
C - Only 34% gave a second preference. So majority did not give a second preference.
Select No, No, No

For a 'majority' to indicate that atleast one of the other options was acceptable, the total of precentages in a particular row (for First Preference) needs to be > 50 %
Option A : 5 + 4 + 3 + 4 = 15 % < 50 %; hence, NO
Option B : 30 + 5 + 4 + 1 = 40 % < 50 % ; hence, NO
Option C : 15 + 4 + 2 + 13 = 34 % < 50 %; hence, NO
NO, NO , NO is the corrrect answer
