Inclusion Criteria

Chronic hepatitis C virus (HCV) infection
- All participants must have HCV genotype 1 or 2 infection, determined at screening
- HCV ribonucleic acid (RNA) plasma levels greater than or equal to (>=)10,000 international units per Milliliter (IU/mL), determined at screening
- Direct-acting antiviral (DAA)-naive participants, defined as not having received treatment with any approved or investigational DAA drug for chronic HCV infection; prior HCV therapy consisting of interferon (IFN, pegylated or nonpegylated) with or without ribavirin (RBV) is allowed
- Participants without cirrhosis or with compensated cirrhosis

Exclusion Criteria

- Infection with HCV genotype - 3, 4, 5, or 6
- Co-infection with human immunodeficiency virus (HIV 1 or HIV 2 antibody positive) or hepatitis B virus (HBV) (hepatitis B surface antigen [HBsAg] positive)
- Prior treatment with any investigational or approved HCV DAA, either in combination with PegIFN or IFN free
- Any evidence of liver disease of non-HCV etiology. This includes, but is not limited to, acute hepatitis A infection (immunoglobulin M), drug or alcohol related liver disease, autoimmune hepatitis, hemochromatosis, Wilson's disease, alpha 1 antitrypsin deficiency, primary biliary cirrhosis, or any other non-HCV liver disease that is considered clinically significant by the investigator
- Evidence of hepatic decompensation as assessed with Child-Pugh Class B or C or any of the following: history or current clinical evidence of ascites, bleeding varices, or hepatic encephalopathy
