All of the following were assigned by Sam Houston to promote the recognition of the Independent Republic of Texas except: a.
William H. Whorton
b.
J. Pickney Henderson
c.
Henry M. Morfit
d.
Memucan Hunt

I think it is C. Henry M. Morfit

Explanation:

I think this would be the answer because whenever I did research onto this subject I found that Sam Houston did not assign Henry out of these answers, hope this helps!

this isn't a question and if you're going to list things be kind and use commas.
