The one that you already have highlighted is correct!
‘Sneezing
uncontrollably‘ is a verb phrase.
<span>
Verbs
are simply known as the ‘action’ words – may it be mental, physical or
mechanical. When verbs are paired with auxiliaries (helping verbs), they are
known as verb phrase. These helping verbs always go first before the actual
verb. We consider it a phrase instead of
‘sneezing’ because of the comma, it emphasized the phrase. Sneezing if it had
been a direct object or subject could be gerund, but unfortunately, not on this
sentence.</span>
