You identify an encryption feature of an application you use. To see how it works, you submit two separate payloads to be encrypted:$$

This is the first test payload$$

This is the second test payload$$

The corresponding encrypted outputs are:$$

$132$c$19$d$6$b$7$d$92632$ab$59974$cf$24573$f$38$ef$6$abc$1637$a$3$d$5$fb$992533541$c$22$f$24$

$132$c$19$d$6$b$7$d$92632$ab$59974$cf$24573$f$3$d$926$d$34$c$9$c$603$a$73$c$4$ce$37$ef$1$dce$8868$

Based on how the output differs from each input, what cipher mode is most likely being utilized?$$

$$

a$.$ Likely CBC$$

b$.$ Likely ECB$$

c$.$ Likely GCM$$
