Explanation

To find the number of females who were not in favour of the proposal, we need to determine the number of females who voted against it. 1. Identify the total number of persons who voted against the proposal: 1226 persons. 2. Identify the number of males who voted against the proposal: 796 males. 3. Subtract the number of males who voted against from the total number of persons who voted against to find the number of females who voted against: Females not in favour (voted against) = Total persons against - Males against Females not in favour = 1226 - 796 = 430 Therefore, 430 females were not in favour of the proposal. Analyzing the options: A) 430: This matches our calculated value for females who voted against the proposal. B) 496: This value does not directly result from the given data for females not in favour. C) 586: This value does not directly result from the given data for females not in favour. D) 1226: This is the total number of persons who voted against the proposal, or the total number of females participating in the survey, not specifically females who were not in favour. The final answer is A) 430
