This question is a bit unclear without any context or information provided. It seems to be asking for the value of a variable or expression represented by "-", "1", "2", and "/".

However, based on the given options, it can be interpreted as follows:

1. The first option is represented by "-", which typically denotes subtraction. However, since there is no number or expression before the "-", it is not possible to perform any subtraction operation. Therefore, this option does not yield a result.

2. The second option is represented by "1". This is a numerical value and does not require any further explanation.

/ ?

The "/" symbol typically represents division. However, since there is no number or expression before the "/", it is not possible to perform any division operation. Therefore, this symbol does not yield a result.

a) 1
b) 2
c) 1 2
d)

The correct answer is option 'C' - "1 2". This means that the result is a combination of both "1" and "2". However, without any additional information or context, it is not clear how these two numbers are related or what operation they represent.

In conclusion, without further information or context, it is difficult to determine the exact meaning or result of the given symbols and numbers. It is important to have more information or clarity in order to provide a more accurate answer.
