A D in transcript

So i got a D in IB Math for the first semester and i am taking other IB classless i have a good GPA and a good extracurricular record and work experience for a non-profit organization. I was wondering if having that one D will impede me from getting into a UC? Thanks

This is from the UC website:

Validation of Grades: “Grade Deficiency” – validation of D or F grades in a lower-level course after completion of a higher-level course with a grade of C or better.

The second semester of a course validates the first semester of that course or lower-level a course, even if the first semester course was at the Honors, AP/IB or College-level.

As a reminder, the original deficient grade (D and F) is still calculated in the GPA for UC freshman admissions.
Note: To remove a grade deficient from the calculation, a repeat of the exact same course is required

If you do not want to D to adversely affect your chances and GPA, I would retake the class.
