How to left align the first col in a table in document class elsearticle?

Question

Hi there I am using class elsarticle. Inserting a table as given below:

  \begin{table*}[h] % final column is twice as wide as first three
    \caption{Dataset Summary Used for the Experiments}
    \begin{tabularx}{\textwidth}{@{} C{1.2}C{0.3}C{0.4} C{2.1} @{}}
        \toprule
        Dataset & Number of speakers & Total utterances & Emotions\\
        \midrule
        Berlin Emotional Speech Database & 10 (5M,~5F) & 535 & Angry, Boredom, Disgust, Fear, Happy, Sadness, Neutral\\
Surrey Audio-Visual Expressed Emotion Database &4 (~4M)& 480&Angry, Disgust, Fear, Happy, Neutral, Sad, Surprised\\
        Ryerson Audio-Visual Database of Emotional Speech and Song&24 (12M,~12F)&1440&Neutral, Calm, Happy, Sad, Angry, Disgust, Surprised\\
        \bottomrule
    \end{tabularx}
\end{table*}

The results I am getting is

I want to align the first col in left. Using l in place of C is not working. Is there any other solution. Also I want (4M) in second col in next line as other two, any help would be appreciated. Regards
