Thank noloader for pointing me in the correction direction. I solved my issue using the following:

String keyStoreType = KeyStore.getDefaultType();
            KeyStore keyStore = KeyStore.getInstance(keyStoreType);
            keyStore.load(null, null);
            keyStore.setCertificateEntry("ca", ca);// my question shows how to get 'ca'
TrustManagerFactory tmf = TrustManagerFactory.getInstance(
    TrustManagerFactory.getDefaultAlgorithm());
// Initialise the TMF as you normally would, for example:
tmf.init(ca); 

TrustManager[] trustManagers = tmf.getTrustManagers();
final X509TrustManager origTrustmanager = (X509TrustManager)trustManagers[0];

TrustManager[] wrappedTrustManagers = new TrustManager[]{
   new X509TrustManager() {
       public java.security.cert.X509Certificate[] getAcceptedIssuers() {
          return origTrustmanager.getAcceptedIssuers();
       }

       public void checkClientTrusted(X509Certificate[] certs, String authType) {
           origTrustmanager.checkClientTrusted(certs, authType);
       }

       public void checkServerTrusted(X509Certificate[] certs, String authType) {
           try {
               origTrustmanager.checkServerTrusted(certs, authType);
           } catch (CertificateExpiredException e) {
               // Do what you need to do, log to Crashlytics?
           }
       }
   }
};

SSLContext sc = SSLContext.getInstance("TLS");
sc.init(null, wrappedTrustManagers, null);
HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());  

Out of the 3 certificates found for the site, mentioned in my question, the one that worked for me was the VeriSign Class 3 Secure Server CA - G3
