Those are the virtualization options.
VTX and VTD are 2 parts of Intel's virtualization tech - CPU and chipset components respectively.
Previously codenamed "Vanderpool", VT-x represents Intel's technology for virtualization on the x86 platform. On November 13, 2005, Intel released two models of Pentium 4 (Model 662 and 672) as the first Intel processors to support VT-x. The CPU flag for VT-x capability is "vmx"; in Linux, this can be checked via /proc/cpuinfo, or in macOS via sysctl machdep.cpu.features.
