To solve this problem, we need to break it down into steps:

Step 1: The average age of the husband and wife when they were married 5 years ago was 23 years. This means that the total age of the husband and wife at the time of their marriage was 2*23 = 46 years.

Step 2: Now, 5 years have passed since their marriage, so the total age of the husband and wife now is 46 years + 5 years (for the husband) + 5 years (for the wife) = 56 years.

Step 3: The problem states that the average age of the husband, the wife, and the child is 20 years now. This means that the total age of the husband, the wife, and the child now is 3*20 = 60 years.

Step 4: To find the age of the child now, we subtract the total age of the husband and wife now from the total age of the husband, wife, and child. So, the age of the child is 60 years - 56 years = 4 years.

So, the answer is a. 4 years.
