Step 1: Write the compound formula.
Acetamide is:
\[
CH_3CONH_2
\] Step 2: Acidic hydrolysis of amides.
Amides on hydrolysis with acid produce carboxylic acid and ammonium salt.
\[
CH_3CONH_2 + H_2O + HCl \rightarrow CH_3COOH + NH_4Cl
\] Step 3: Identify the organic product.
The main organic product is acetic acid (CH\(_3\)COOH). Final Answer:
\[
\boxed{\text{(A) acetic acid}}
\]
