To complete the sentence correctly, we need to choose the option that maintains grammatical accuracy and conveys the intended meaning. The sentence states: "That bike is going __________ if you don’t lock it up."

Here's the analysis of each option:

1. a. to stealing - This option does not fit grammatically within the sentence.
2. b. NONE OF THE GIVEN OPTIONS - We need to check if the remaining options are valid before deciding this.
3. c. to steald - This is a typographical error; "steald" is not a valid word.
4. d. to be stolen - This option is grammatically correct and conveys that the bike is at risk of being taken by someone if it's not locked up.

Final Answer

The correct answer is d. to be stolen.
