How would a temperature of 4.3 be encoded in column 11?

In weather reporting systems, temperatures are often encoded in a specific format to standardize how they are presented. In the case of encoding a temperature of 4.3 degrees, the correct answer pertains to the requirement of representing temperatures in two digits.

The format typically requires that the temperature be presented as two digits, where the leading digit can be a zero. In this instance, since the temperature is less than 10, it is crucial to include the leading zero to meet the two-digit format. Thus, a temperature of 4.3 degrees would be encoded simply as 04. This method ensures clarity and consistency when reading or interpreting the encoded data, especially when temperatures may vary widely.

The other options do not fit the encoding standard required for column 11. For instance, encoding it as 43 would incorrectly represent the temperature as 43 degrees, while 04.3 includes an unnecessary decimal point and is not in the two-digit integer format required. Similarly, 4.0 does not adhere to the two-digit requirement since it lacks the leading zero.
