Attitudinal Barriers to effective listening are -OptionsAll the abovehearing problemsegocentrismsmoke

The question seems to be asking about the attitudinal barriers to effective listening. The options provided are:

1. All the above
2. Hearing problems
3. Egocentrism
4. Smoke

However, the options are not clearly defined. Here's a brief explanation of each:

1. All the above: This option suggests that all the listed items are attitudinal barriers to effective listening.

2. Hearing problems: This is more of a physical barrier than an attitudinal one. If a person has hearing problems, they may not be able to listen effectively, but this is not due to their attitude.

3. Egocentrism: This is indeed an attitudinal barrier to effective listening. If a person is egocentric, they tend to focus on their own thoughts and views and ignore those of others, which can prevent them from listening effectively.

4. Smoke: This seems unrelated to the topic. Smoke can be a physical barrier to communication if it interferes with a person's ability to see or breathe, but it's not an attitudinal barrier to effective listening.

So, based on the given options, only egocentrism is an attitudinal barrier to effective listening.
