I'll analyze and solve each question in the image.

### Question 1
It involves a triangle with a specified angle measurement at point \( O \). We need to determine the measure of angle \( C \) based on given information. Since the triangle is labeled with angles \( 40^\circ \) at point \( B \) and \( 11^\circ \) at point \( D \), we should apply the angle sum property in triangles and any additional information to find the correct answer.

#### Solution:
1. If we consider \( \angle C \) as an external angle or use the angle properties in triangles, we can sum the given angles and solve for \( \angle C \).
2. The answer is likely among the options: \( 10^\circ, 20^\circ, 30^\circ, 40^\circ \).

### Question 2
This question gives a set of inequalities and equalities between segments \( MN, EF, AB, \) and \( GH \). We are asked to deduce a relationship from the given conditions.

#### Solution:
1. We have \( MN = EF \), \( EF < AB \), and \( AB = GH \).
2. With \( EF < AB = GH \), it implies \( EF < GH \).
3. This rules out the equality options and suggests the inequality options should be evaluated.

### Question 3
The problem involves a divided line \( AB \) with points marked \( C, D, E, F, G \), dividing it into six equal segments. We need to determine which of the given relations is incorrect.

#### Solution:
1. By analyzing the segment lengths, if each segment (e.g., \( AC, CD, DE \)) is equal, we can check each relation.
2. Relations include proportions like \( \frac{CF}{FB} = \frac{1}{2} \), and others, which can be tested for accuracy based on equal segment division.
